-<h2>
-<a NAME="Introduction"></a>Introduction</h2>
-This is the README file for the&nbsp;<span CLASS=LXRSHORTDESC>JavaScript
-Reference (JSRef) implementation.</span> It consists of build conventions
-and instructions, source code conventions, a design walk-through, and a
-brief file-by-file description of the source.
-<p><span CLASS=LXRLONGDESC>JSRef builds a library or DLL containing the
-JavaScript runtime (compiler, interpreter, decompiler, garbage collector,
-atom manager, standard classes). It then compiles a small "shell" program
-and links that with the library to make an interpreter that can be used
-interactively and with test .js files to run scripts.&nbsp; The code has
-no dependencies on the Navigator code.</span>
-<p><i>Quick start tip</i>: skip to "Using the JS API" below, build the
-js shell, and play with the object named "it" (start by setting 'it.noisy
-= true').
-<h2>
-<a NAME="Build"></a>Build conventions (standalone JS engine and shell)</h2>
-These build directions refer only to building the standalone JavaScript
-engine and shell.&nbsp; To build within the browser, refer to the <a href="http://www.mozilla.org/docs/">build
-directions</a> on the mozilla.org website.
-<p>By default, all platforms build a version of the JS engine that is <i>not</i>
-threadsafe.&nbsp; If you require thread-safety, you must also populate
-the <tt>mozilla/dist</tt> directory with <a href="http://www.mozilla.org/docs/tplist/catCode/nsprdesc.htm">NSPR</a>
-headers and libraries.&nbsp; (NSPR implements a portable threading library,
-among other things.&nbsp; The source is downloadable via <a href="http://www.mozilla.org/cvs.html">CVS</a>
-from <tt><a href="http://lxr.mozilla.org/mozilla/source/nsprpub">mozilla/nsprpub</a></tt>.)&nbsp;
-Next, you must define <tt>JS_THREADSAFE</tt> when building the JS engine,
-either on the command-line (gmake/nmake) or in a universal header file.
-<h3>
-Windows</h3>
-
-<ul>
-<li>
-Use MSVC 4.2 or 5.0.</li>
-
-<li>
-For building from the IDE use <tt>js/src/js.mdp</tt>.&nbsp; (<tt>js.mdp</tt>
-is an MSVC4.2 project file, but if you load it into MSVC5, it will be converted
-to the newer project file format.)&nbsp; <font color="#CC0000">NOTE: makefile.win
-is an nmake file used only for building the JS-engine in the Mozilla browser.&nbsp;
-Don't attempt to use it to build the standalone JS-engine.</font></li>
-
-<li>
-If you prefer to build from the command-line, use '<tt>nmake -f js.mak</tt>'</li>
-
-<li>
-Executable shell <tt>js.exe</tt> and runtime library <tt>js32.dll</tt>
-are created in either <tt>js/src/Debug</tt> or <tt>js/src/Release</tt>.</li>
-</ul>
-
-<h3>
-Macintosh</h3>
-
-<ul>
-<li>
-Use CodeWarrior 3.x</li>
-
-<li>
-Load the project file <tt>js:src:macbuild:JSRef.mcp </tt>and select "Make"
-from the menu.</li>
-</ul>
-
-<h3>
-Unix</h3>
-
-<ul>
-<li>
-Use '<tt>gmake -f Makefile.ref</tt>' to build. To compile optimized code,
-pass <tt>BUILD_OPT=1</tt> on the gmake command line or preset it in the
-environment or <tt>Makefile.ref</tt>.&nbsp; <font color="#CC0000">NOTE:
-Do not attempt to use Makefile to build the standalone JavaScript engine.&nbsp;
-This file is used only for building the JS-engine in the Mozilla browser.</font></li>
-
-<li>
-<font color="#000000">Each platform on which JS is built must have a <tt>*.mk</tt>
-configuration file in the <tt>js/src/config</tt> directory.&nbsp; The configuration
-file specifies the compiler/linker to be used and allows for customization
-of command-line options.&nbsp; To date, the build system has been tested
-on Solaris, AIX, HP/UX, OSF, IRIX, x86 Linux and Windows NT.</font></li>
-
-<li>
-<font color="#000000">Most platforms will work with either the vendor compiler
-</font>or
-<a href="ftp://prep.ai.mit.edu/pub/gnu">gcc</a>.&nbsp;
-(Except that HP builds only work using the native compiler.&nbsp; gcc won't
-link correctly with shared libraries on that platform.&nbsp; If someone
-knows a way to fix this, <a href="mailto:wynholds@netscape.com">let us
-know</a>.)</li>
-
-<li>
-<font color="#000000">If you define <tt>JS_LIVECONNECT</tt>, gmake will
-descend into the liveconnect directory and build 
-<a href="http://lxr.mozilla.org/mozilla/source/js/src/liveconnect/README.html">LiveConnect</a>
-after building the JS engine.</font></li>
-
-<li>
-To build a binary drop (a zip'ed up file of headers, libraries, binaries),
-check out <tt>mozilla/config</tt> and <tt>mozilla/nsprpub/config</tt>.&nbsp;
-Use '<tt>gmake -f Makefile.ref nsinstall-target all export ship</tt>'</li>
-</ul>
-
-<h2>
-<a NAME="Debugging"></a>Debugging notes</h2>
-
-<ul>
-<li>
-To turn on GC instrumentation, define <tt>JS_GCMETER</tt>.</li>
-
-<li>
-To turn on the arena package's instrumentation, define <tt>JS_ARENAMETER</tt>.</li>
-
-<li>
-To turn on the hash table package's metering, define <tt>JS_HASHMETER</tt>.</li>
-</ul>
-
-<h2>
-<a NAME="Conventions"></a>Naming and coding conventions</h2>
-
-<ul>
-<li>
-Public function names begin with <tt>JS_</tt> followed by capitalized "intercaps",
-e.g. <tt>JS_NewObject</tt>.</li>
-
-<li>
-Extern but library-private function names use a <tt>js_</tt> prefix and
-mixed case, e.g. <tt>js_LookupSymbol</tt>.</li>
-
-<li>
-Most static function names have unprefixed, mixed-case names: <tt>GetChar</tt>.</li>
-
-<li>
-But static native methods of JS objects have lowercase, underscore-separated
-or intercaps names, e.g., <tt>str_indexOf</tt>.</li>
-
-<li>
-And library-private and static data use underscores, not intercaps (but
-library-private data do use a <tt>js_</tt> prefix).</li>
-
-<li>
-Scalar type names are lowercase and js-prefixed: <tt>jsdouble</tt>.</li>
-
-<li>
-Aggregate type names are JS-prefixed and mixed-case: <tt>JSObject.</tt></li>
-
-<li>
-Macros are generally <tt>ALL_CAPS </tt>and underscored, to call out potential
-side effects, multiple uses of a formal argument, etc. - Four spaces of
-indentation per statement nesting level.</li>
-
-<li>
-Tabs are taken to be eight spaces, and an Emacs magic comment at the top
-of each file tries to help. If you're using MSVC or similar, you'll want
-to set tab width to 8, or convert these files to be space-filled.</li>
-
-<li>
-DLL entry points have their return type expanded within a <tt>JS_PUBLIC_API()</tt>
-macro call, to get the right Windows secret type qualifiers in the right
-places for both 16- and 32-bit builds.</li>
-
-<li>
-Callback functions that might be called from a DLL are similarly macroized
-with <tt>JS_STATIC_DLL_CALLBACK</tt> (if the function otherwise would be
-static to hide its name) or <tt>JS_DLL_CALLBACK</tt> (this macro takes
-no type argument; it should be used after the return type and before the
-function name).</li>
-</ul>

-<p>JavaScript uses untyped bytecode and runtime type tagging of data values.
-The <tt>jsval</tt> type is a signed machine word that contains either a
-signed integer value (if the low bit is set), or a type-tagged pointer
-or boolean value (if the low bit is clear). Tagged pointers all refer to
-8-byte-aligned things in the GC heap.
-<p>Objects consist of a possibly shared structural description, called
-the map or scope; and unshared property values in a vector, called the
-slots. Object properties are associated with nonnegative integers stored
-in <tt>jsval</tt>'s, or with atoms (unique string descriptors) if named
-by an identifier or a non-integral index expression.
-<p>Scripts contain bytecode, source annotations, and a pool of string,
-number, and identifier literals. Functions are objects that extend scripts
-or native functions with formal parameters, a literal syntax, and a distinct
-primitive type ("function").
-<p>The compiler consists of a recursive-descent parser and a random-logic
-rather than table-driven lexical scanner. Semantic and lexical feedback
-are used to disambiguate hard cases such as missing semicolons, assignable
-expressions ("lvalues" in C parlance), etc. The parser generates bytecode
-as it parses, using fixup lists for downward branches and code buffering
-and rewriting for exceptional cases such as for loops. It attempts no error
-recovery. The interpreter executes the bytecode of top-level scripts, and
-calls itself indirectly to interpret function bodies (which are also scripts).
-All state associated with an interpreter instance is passed through formal
-parameters to the interpreter entry point; most implicit state is collected
-in a type named JSContext. Therefore, all API and almost all other functions
-in JSRef take a JSContext pointer as their first argument.
-<p>The decompiler translates postfix bytecode into infix source by consulting
-a separate byte-sized code, called source notes, to disambiguate bytecodes
-that result from more than one grammatical production.
-<p>The GC is a mark-and-sweep, non-conservative (perfect) collector. It
-can allocate only fixed-sized things -- the current size is two machine
-words. It is used to hold JS object and string descriptors (but not property
-lists or string bytes), and double-precision floating point numbers. It
-runs automatically only when maxbytes (as passed to <tt>JS_Init()</tt>)
-bytes of GC things have been allocated and another thing-allocation request
-is made. JS API users should call <tt>JS_GC()</tt> or <tt>JS_MaybeGC()</tt>
-between script executions or from the branch callback, as often as necessary.
-<p>An important point about the GC's "perfection": you must add roots for
-new objects created by your native methods if you store references to them
-into a non-JS structure in the malloc heap or in static data. Also, if
-you make a new object in a native method, but do not store it through the
-<tt>rval</tt>
-result parameter (see math_abs in the "Using the JS API" section above)
-so that it is in a known root, the object is guaranteed to survive only
-until another new object is created. Either lock the first new object when
-making two in a row, or store it in a root you've added, or store it via
-rval.
-<p>The atom manager consists of a hash table associating strings uniquely
-with scanner/parser information such as keyword type, index in script or
-function literal pool, etc. Atoms play three roles in JSRef: as literals
-referred to by unaligned 16-bit immediate bytecode operands, as unique
-string descriptors for efficient property name hashing, and as members
-of the root GC set for perfect GC. This design therefore requires atoms
-to be manually reference counted, from script literal pools (<tt>JSAtomMap</tt>)
-and object symbol (<tt>JSSymbol</tt>) entry keys.
-<p>Native objects and methods for arrays, booleans, dates, functions, numbers,
-and strings are implemented using the JS API and certain internal interfaces
-used as "fast paths".
-<p>In general, errors are signaled by false or unoverloaded-null return
-values, and are reported using <tt>JS_ReportError()</tt> or one of its
-variants by the lowest level in order to provide the most detail. Client
-code can substitute its own error reporting function and suppress errors,
-or reflect them into Java or some other runtime system as exceptions, GUI
-dialogs, etc..
-<h2>
-File walk-through (BADLY OUT OF DATE!)</h2>
-
-<h4>
-jsapi.c, jsapi.h</h4>
-The public API to be used by almost all client code.&nbsp; If your client
-code can't make do with <tt>jsapi.h</tt>, and must reach into a friend
-or private js* file, please let us know so we can extend <tt>jsapi.h</tt>
-to include what you need in a fashion that we can support over the long
-run.
-<h4>
-jspubtd.h, jsprvtd.h</h4>
-These files exist to group struct and scalar typedefs so they can be used
-everywhere without dragging in struct definitions from N different files.
-The <tt>jspubtd.h</tt> file contains public typedefs, and is included by
-<tt>jsapi.h</tt>.
-The <tt>jsprvtd.h</tt> file contains private typedefs and is included by
-various .h files that need type names, but not type sizes or declarations.
-<h4>
-jsdbgapi.c, jsdbgapi.h</h4>
-The Debugging API, still very much under development. Provided so far:
-<ul>
-<li>
-Traps, with which breakpoints, single-stepping, step over, step out, and
-so on can be implemented. The debugger will have to consult jsopcode.def
-on its own to figure out where to plant trap instructions to implement
-functions like step out, but a future jsdbgapi.h will provide convenience
-interfaces to do these things. At most one trap per bytecode can be set.
-When a script (<tt>JSScript</tt>) is destroyed, all traps set in its bytecode
-are cleared.</li>
-
-<li>
-Watchpoints, for intercepting set operations on properties and running
-a debugger-supplied function that receives the old value and a pointer
-to the new one, which it can use to modify the new value being set.</li>
-
-<li>
-Line number to PC and back mapping functions. The line-to-PC direction
-"rounds" toward the next bytecode generated from a line greater than or
-equal to the input line, and may return the PC of a for-loop update part,
-if given the line number of the loop body's closing brace. Any line after
-the last one in a script or function maps to a PC one byte beyond the last
-bytecode in the script. An example, from perfect.js:</li>
-
-<pre><tt>14&nbsp;&nbsp; function perfect(n)
-15&nbsp;&nbsp; {
-16&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("The perfect numbers up to " +&nbsp; n + " are:");
-17
-18&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // We build sumOfDivisors[i] to hold a string expression for
-19&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // the sum of the divisors of i, excluding i itself.
-20&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; var sumOfDivisors = new ExprArray(n+1,1);
-21&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (var divisor = 2; divisor &lt;= n; divisor++) {
-22&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (var j = divisor + divisor; j &lt;= n; j += divisor) {
-23&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; sumOfDivisors[j] += " + " + divisor;
-24&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
-25&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // At this point everything up to 'divisor' has its sumOfDivisors
-26&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // expression calculated, so we can determine whether it's perfect
-27&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // already by evaluating.
-28&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (eval(sumOfDivisors[divisor]) == divisor) {
-29&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("" + divisor + " = " + sumOfDivisors[divisor]);
-30&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
-31&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
-32&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; delete sumOfDivisors;
-33&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("That's all.");
-34&nbsp;&nbsp; }</tt></pre>
-The line number to PC and back mappings can be tested using the js program
-with the following script:
-<pre><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; load("perfect.js")
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print(perfect)
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; dis(perfect)
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print()
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (var ln = 0; ln &lt;= 40; ln++) {
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; var pc = line2pc(perfect,ln)
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; var ln2 = pc2line(perfect,pc)
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("\tline " + ln + " => pc " + pc + " => line " + ln2)
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }</tt></pre>
-The result of the for loop over lines 0 to 40 inclusive is:
-<pre><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; line 0 => pc 0 => line 16
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; line 1 => pc 0 => line 16

-</ul>
-
-<h4>
-jsconfig.h</h4>
-Various configuration macros defined as 0 or 1 depending on how <tt>JS_VERSION</tt>
-is defined (as 10 for JavaScript 1.0, 11 for JavaScript 1.1, etc.). Not
-all macros are tested around related code yet. In particular, JS 1.0 support
-is missing from JSRef. JS 1.2 support will appear in a future JSRef release.
-<br>&nbsp;
-<h4>
-js.c</h4>
-The "JS shell", a simple interpreter program that uses the JS API and more
-than a few internal interfaces (some of these internal interfaces could
-be replaced by <tt>jsapi.h</tt> calls). The js program built from this
-source provides a test vehicle for evaluating scripts and calling functions,
-trying out new debugger primitives, etc.
-<h4>
-jsarray.*, jsbool.*, jdsdate.*, jsfun.*, jsmath.*, jsnum.*, jsstr.*</h4>
-These file pairs implement the standard classes and (where they exist)
-their underlying primitive types. They have similar structure, generally
-starting with class definitions and continuing with internal constructors,
-finalizers, and helper functions.
-<h4>
-jsobj.*, jsscope.*</h4>
-These two pairs declare and implement the JS object system. All of the
-following happen here:
-<ul>
-<li>
-creating objects by class and prototype, and finalizing objects;</li>
-
-<li>
-defining, looking up, getting, setting, and deleting properties;</li>
-
-<li>
-creating and destroying properties and binding names to them.</li>
-</ul>
-The details of an object map (scope) are mostly hidden in <tt>jsscope.[ch]</tt>,
-where scopes start out as linked lists of symbols, and grow after some
-threshold into PR hash tables.
-<h4>
-jsatom.c, jsatom.h</h4>
-The atom manager. Contains well-known string constants, their atoms, the
-global atom hash table and related state, the js_Atomize() function that
-turns a counted string of bytes into an atom, and literal pool (<tt>JSAtomMap</tt>)
-methods.
-<h4>
-jsgc.c, jsgc.h</h4>
-[TBD]
-<h4>
-jsinterp.*, jscntxt.*</h4>
-The bytecode interpreter, and related functions such as Call and AllocStack,
-live in <i>jsinterp.c</i>. The JSContext constructor and destructor are
-factored out into <i>jscntxt.c</i> for minimal linking when the compiler
-part of JS is split from the interpreter part into a separate program.
-<h4>
-jsemit.*, jsopcode.tbl, jsopcode.*, jsparse.*, jsscan.*, jsscript.*</h4>
-Compiler and decompiler modules. The <i>jsopcode.tbl</i> file is a C preprocessor
-source that defines almost everything there is to know about JS bytecodes.
-See its major comment for how to use it. For now, a debugger will use it
-and its dependents such as <i>jsopcode.h</i> directly, but over time we
-intend to extend <i>jsdbgapi.h</i> to hide uninteresting details and provide
-conveniences. The code generator is split across paragraphs of code in
-<i>jsparse.c</i>,
-and the utility methods called on <tt>JSCodeGenerator</tt> appear in <i>jsemit.c</i>.
-Source notes generated by <i>jsparse.c</i> and
-<i>jsemit.c</i> are used
-in <i>jsscript.c</i> to map line number to program counter and back.
-<h4>
-jstypes.h, jslog2.c</h4>
-Fundamental representation types and utility macros. This file alone among
-all .h files in JSRef must be included first by .c files. It is not nested
-in .h files, as other prerequisite .h files generally are, since it is
-also a direct dependency of most .c files and would be over-included if
-nested in addition to being directly included. The one "not-quite-a-macro
-macro" is the <tt>JS_CeilingLog2()</tt> function in <i>jslog2.c</i>.
-<h4>
-jsarena.c, jsarena.h</h4>
-Last-In-First-Out allocation macros that amortize malloc costs and allow
-for en-masse freeing. See the paper mentioned in prarena.h's major comment.
-<h4>
-jsutil.c, jsutil.h</h4>
-The <tt>JS_ASSERT</tt> macro is used throughout JSRef source as a proof
-device to make invariants and preconditions clear to the reader, and to
-hold the line during maintenance and evolution against regressions or violations
-of assumptions that it would be too expensive to test unconditionally at
-run-time. Certain assertions are followed by run-time tests that cope with
-assertion failure, but only where I'm too smart or paranoid to believe
-the assertion will never fail...
-<h4>
-jsclist.h</h4>
-Doubly-linked circular list struct and macros.
-<h4>
-jscpucfg.c</h4>
-This standalone program generates <i>jscpucfg.h</i>, a header file containing
-bytes per word and other constants that depend on CPU architecture and
-C compiler type model. It tries to discover most of these constants by
-running its own experiments on the build host, so if you are cross-compiling,
-beware.
-<h4>
-prdtoa.c, prdtoa.h</h4>
-David Gay's portable double-precision floating point to string conversion
-code, with Permission To Use notice included.
-<h4>
-prhash.c, prhash.h</h4>
-Portable, extensible hash tables. These use multiplicative hash for strength
-reduction over division hash, yet with very good key distribution over
-power of two table sizes. Collisions resolve via chaining, so each entry
-burns a malloc and can fragment the heap.
-<h4>
-prlong.c, prlong.h</h4>
-64-bit integer emulation, and compatible macros that use C's long long
-type where it exists (my last company mapped long long to a 128-bit type,
-but no real architecture does 128-bit ints yet).
-<h4>
-jsosdep.h</h4>
-Annoying OS dependencies rationalized into a few "feature-test" macros
-such as <tt>JS_HAVE_LONG_LONG</tt>.
-<h4>
-jsprf.*</h4>
-Portable, buffer-overrun-resistant sprintf and friends. For no good reason
-save lack of time, the %e, %f, and %g formats cause your system's native
-sprintf, rather than <tt>JS_dtoa()</tt>, to be used. This bug doesn't affect
-JSRef, because it uses its own <tt>JS_dtoa()</tt> call in <i>jsnum.c</i>
-to convert from double to string, but it's a bug that we'll fix later,
-and one you should be aware of if you intend to use a <tt>JS_*printf()</tt>&nbsp;
-function with your own floating type arguments - various vendor sprintf's
-mishandle NaN, +/-Inf, and some even print normal floating values inaccurately.
-<h4>
-prmjtime.c, prmjtime.h</h4>
-Time functions. These interfaces are named in a way that makes local vs.
-universal time confusion likely. Caveat emptor, and we're working on it.
-To make matters worse, Java (and therefore JavaScript) uses "local" time
-numbers (offsets from the epoch) in its Date class.

-# There are two options in making libm at fdlibm compile time:
-#       _IEEE_LIBM      --- IEEE libm; smaller, and somewhat faster
-#       _MULTI_LIBM     --- Support multi-standard at runtime by 
-#                           imposing wrapper functions defined in 
-#                           fdlibm.h:

-#       CFLAGS = -D_SVID3_MODE  ... Multi-standard supported
-#                                           libm with SVID as the 
-#                                           default standard

-#                                           default standard
-#       CFLAGS = -D_POSIX_MODE  ... Multi-standard supported
-#                                           libm with POSIX as the 
-#                                           default standard

-/* __ieee754_exp(x)
- * Returns the exponential of x.
- *
- * Method
- *   1. Argument reduction:
- *      Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
- *	Given x, find r and integer k such that
- *
- *               x = k*ln2 + r,  |r| <= 0.5*ln2.  
- *
- *      Here r will be represented as r = hi-lo for better 
- *	accuracy.
- *
- *   2. Approximation of exp(r) by a special rational function on
- *	the interval [0,0.34658]:
- *	Write
- *	    R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
- *      We use a special Reme algorithm on [0,0.34658] to generate 
- * 	a polynomial of degree 5 to approximate R. The maximum error 
- *	of this polynomial approximation is bounded by 2**-59. In
- *	other words,
- *	    R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
- *  	(where z=r*r, and the values of P1 to P5 are listed below)
- *	and
- *	    |                  5          |     -59
- *	    | 2.0+P1*z+...+P5*z   -  R(z) | <= 2 
- *	    |                             |
- *	The computation of exp(r) thus becomes
- *                             2*r
- *		exp(r) = 1 + -------
- *		              R - r
- *                                 r*R1(r)	
- *		       = 1 + r + ----------- (for better accuracy)
- *		                  2 - R1(r)
- *	where
- *			         2       4             10
- *		R1(r) = r - (P1*r  + P2*r  + ... + P5*r   ).
- *	
- *   3. Scale back to obtain exp(x):
- *	From step 1, we have
- *	   exp(x) = 2^k * exp(r)
- *
- * Special cases:
- *	exp(INF) is INF, exp(NaN) is NaN;
- *	exp(-INF) is 0, and
- *	for finite argument, only exp(0)=1 is exact.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Misc. info.
- *	For IEEE double 
- *	    if x >  7.09782712893383973096e+02 then exp(x) overflow
- *	    if x < -7.45133219101941108420e+02 then exp(x) underflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

- *	If (assume round-to-nearest) z=x*x+y*y 
- *	has error less than sqrt(2)/2 ulp, than 
- *	sqrt(z) has error less than 1 ulp (exercise).
- *
- *	So, compute sqrt(x*x+y*y) with some care as

- *
- *	Assume x>y>0;
- *	(if possible, set rounding to round-to-nearest)
- *	1. if x > 2y  use

- *	NOTE: scaling may be necessary if some argument is too

- * Special cases:

- * Bessel function of the first and second kinds of order zero.
- * Method -- j0(x):
- *	1. For tiny x, we use j0(x) = 1 - x^2/4 + x^4/64 - ...
- *	2. Reduce x to |x| since j0(x)=j0(-x),  and
- *	   for x in (0,2)
- *		j0(x) = 1-z/4+ z^2*R0/S0,  where z = x*x;
- *	   (precision:  |j0-1+z/4-z^2R0/S0 |<2**-63.67 )
- *	   for x in (2,inf)
- * 		j0(x) = sqrt(2/(pi*x))*(p0(x)*cos(x0)-q0(x)*sin(x0))
- * 	   where x0 = x-pi/4. It is better to compute sin(x0),cos(x0)
- *	   as follow:
- *		cos(x0) = cos(x)cos(pi/4)+sin(x)sin(pi/4)
- *			= 1/sqrt(2) * (cos(x) + sin(x))
- *		sin(x0) = sin(x)cos(pi/4)-cos(x)sin(pi/4)
- *			= 1/sqrt(2) * (sin(x) - cos(x))
- * 	   (To avoid cancellation, use
- *		sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
- * 	    to compute the worse one.)
- *	   
- *	3 Special cases
- *		j0(nan)= nan
- *		j0(0) = 1
- *		j0(inf) = 0
- *		
- * Method -- y0(x):
- *	1. For x<2.
- *	   Since 
- *		y0(x) = 2/pi*(j0(x)*(ln(x/2)+Euler) + x^2/4 - ...)
- *	   therefore y0(x)-2/pi*j0(x)*ln(x) is an even function.
- *	   We use the following function to approximate y0,
- *		y0(x) = U(z)/V(z) + (2/pi)*(j0(x)*ln(x)), z= x^2
- *	   where 
- *		U(z) = u00 + u01*z + ... + u06*z^6
- *		V(z) = 1  + v01*z + ... + v04*z^4
- *	   with absolute approximation error bounded by 2**-72.
- *	   Note: For tiny x, U/V = u0 and j0(x)~1, hence
- *		y0(tiny) = u0 + (2/pi)*ln(tiny), (choose tiny<2**-27)
- *	2. For x>=2.
- * 		y0(x) = sqrt(2/(pi*x))*(p0(x)*cos(x0)+q0(x)*sin(x0))
- * 	   where x0 = x-pi/4. It is better to compute sin(x0),cos(x0)
- *	   by the method mentioned above.
- *	3. Special cases: y0(0)=-inf, y0(x<0)=NaN, y0(inf)=0.

-/* __ieee754_j1(x), __ieee754_y1(x)
- * Bessel function of the first and second kinds of order zero.
- * Method -- j1(x):
- *	1. For tiny x, we use j1(x) = x/2 - x^3/16 + x^5/384 - ...
- *	2. Reduce x to |x| since j1(x)=-j1(-x),  and
- *	   for x in (0,2)
- *		j1(x) = x/2 + x*z*R0/S0,  where z = x*x;
- *	   (precision:  |j1/x - 1/2 - R0/S0 |<2**-61.51 )
- *	   for x in (2,inf)
- * 		j1(x) = sqrt(2/(pi*x))*(p1(x)*cos(x1)-q1(x)*sin(x1))
- * 		y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
- * 	   where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
- *	   as follow:
- *		cos(x1) =  cos(x)cos(3pi/4)+sin(x)sin(3pi/4)
- *			=  1/sqrt(2) * (sin(x) - cos(x))
- *		sin(x1) =  sin(x)cos(3pi/4)-cos(x)sin(3pi/4)
- *			= -1/sqrt(2) * (sin(x) + cos(x))
- * 	   (To avoid cancellation, use
- *		sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
- * 	    to compute the worse one.)
- *	   
- *	3 Special cases
- *		j1(nan)= nan
- *		j1(0) = 0
- *		j1(inf) = 0
- *		
- * Method -- y1(x):
- *	1. screen out x<=0 cases: y1(0)=-inf, y1(x<0)=NaN 
- *	2. For x<2.
- *	   Since 
- *		y1(x) = 2/pi*(j1(x)*(ln(x/2)+Euler)-1/x-x/2+5/64*x^3-...)
- *	   therefore y1(x)-2/pi*j1(x)*ln(x)-1/x is an odd function.
- *	   We use the following function to approximate y1,
- *		y1(x) = x*U(z)/V(z) + (2/pi)*(j1(x)*ln(x)-1/x), z= x^2
- *	   where for x in [0,2] (abs err less than 2**-65.89)
- *		U(z) = U0[0] + U0[1]*z + ... + U0[4]*z^4
- *		V(z) = 1  + v0[0]*z + ... + v0[4]*z^5
- *	   Note: For tiny x, 1/x dominate y1 and hence
- *		y1(tiny) = -2/pi/tiny, (choose tiny<2**-54)
- *	3. For x>=2.
- * 		y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
- * 	   where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
- *	   by method mentioned above.

-/* __ieee754_lgamma_r(x, signgamp)
- * Reentrant version of the logarithm of the Gamma function 
- * with user provide pointer for the sign of Gamma(x). 
- *
- * Method:
- *   1. Argument Reduction for 0 < x <= 8
- * 	Since gamma(1+s)=s*gamma(s), for x in [0,8], we may 
- * 	reduce x to a number in [1.5,2.5] by
- * 		lgamma(1+s) = log(s) + lgamma(s)
- *	for example,
- *		lgamma(7.3) = log(6.3) + lgamma(6.3)
- *			    = log(6.3*5.3) + lgamma(5.3)
- *			    = log(6.3*5.3*4.3*3.3*2.3) + lgamma(2.3)
- *   2. Polynomial approximation of lgamma around its
- *	minimun ymin=1.461632144968362245 to maintain monotonicity.
- *	On [ymin-0.23, ymin+0.27] (i.e., [1.23164,1.73163]), use
- *		Let z = x-ymin;
- *		lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
- *	where
- *		poly(z) is a 14 degree polynomial.
- *   2. Rational approximation in the primary interval [2,3]
- *	We use the following approximation:
- *		s = x-2.0;
- *		lgamma(x) = 0.5*s + s*P(s)/Q(s)
- *	with accuracy
- *		|P/Q - (lgamma(x)-0.5s)| < 2**-61.71
- *	Our algorithms are based on the following observation
- *
- *                             zeta(2)-1    2    zeta(3)-1    3
- * lgamma(2+s) = s*(1-Euler) + --------- * s  -  --------- * s  + ...
- *                                 2                 3
- *
- *	where Euler = 0.5771... is the Euler constant, which is very
- *	close to 0.5.
- *
- *   3. For x>=8, we have
- *	lgamma(x)~(x-0.5)log(x)-x+0.5*log(2pi)+1/(12x)-1/(360x**3)+....
- *	(better formula:
- *	   lgamma(x)~(x-0.5)*(log(x)-1)-.5*(log(2pi)-1) + ...)
- *	Let z = 1/x, then we approximation
- *		f(z) = lgamma(x) - (x-0.5)(log(x)-1)
- *	by
- *	  			    3       5             11
- *		w = w0 + w1*z + w2*z  + w3*z  + ... + w6*z
- *	where 
- *		|w - f(z)| < 2**-58.74
- *		
- *   4. For negative x, since (G is gamma function)
- *		-x*G(-x)*G(x) = pi/sin(pi*x),
- * 	we have
- * 		G(x) = pi/(sin(pi*x)*(-x)*G(-x))
- *	since G(-x) is positive, sign(G(x)) = sign(sin(pi*x)) for x<0
- *	Hence, for x<0, signgam = sign(sin(pi*x)) and 
- *		lgamma(x) = log(|Gamma(x)|)
- *			  = log(pi/(|x*sin(pi*x)|)) - lgamma(-x);
- *	Note: one should avoid compute pi*(-x) directly in the 
- *	      computation of sin(pi*(-x)).
- *		
- *   5. Special Cases
- *		lgamma(2+s) ~ s*(1-Euler) for tiny s
- *		lgamma(1)=lgamma(2)=0
- *		lgamma(x) ~ -log(x) for tiny x
- *		lgamma(0) = lgamma(inf) = inf
- *	 	lgamma(-integer) = +-inf

-/* __ieee754_log(x)
- * Return the logrithm of x
- *
- * Method :                  
- *   1. Argument Reduction: find k and f such that 
- *			x = 2^k * (1+f), 
- *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
- *
- *   2. Approximation of log(1+f).
- *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
- *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- *	     	 = 2s + s*R
- *      We use a special Reme algorithm on [0,0.1716] to generate 
- * 	a polynomial of degree 14 to approximate R The maximum error 
- *	of this polynomial approximation is bounded by 2**-58.45. In
- *	other words,
- *		        2      4      6      8      10      12      14
- *	    R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s  +Lg6*s  +Lg7*s
- *  	(the values of Lg1 to Lg7 are listed in the program)
- *	and
- *	    |      2          14          |     -58.45
- *	    | Lg1*s +...+Lg7*s    -  R(z) | <= 2 
- *	    |                             |
- *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
- *	In order to guarantee error in log below 1ulp, we compute log
- *	by
- *		log(1+f) = f - s*(f - R)	(if f is not too large)
- *		log(1+f) = f - (hfsq - s*(hfsq+R)).	(better accuracy)
- *	
- *	3. Finally,  log(x) = k*ln2 + log(1+f).  
- *			    = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
- *	   Here ln2 is split into two floating point number: 
- *			ln2_hi + ln2_lo,
- *	   where n*ln2_hi is always exact for |n| < 2000.
- *
- * Special cases:
- *	log(x) is NaN with signal if x < 0 (including -INF) ; 
- *	log(+INF) is +INF; log(0) is -INF with signal;
- *	log(NaN) is that NaN with no signal.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough 
- * to produce the hexadecimal values shown.

- * Return the base 10 logarithm of x
- * 
- * Method :
- *	Let log10_2hi = leading 40 bits of log10(2) and
- *	    log10_2lo = log10(2) - log10_2hi,
- *	    ivln10   = 1/log(10) rounded.

- *		log10(x) := n*log10_2hi + (n*log10_2lo + ivln10*log(x))
- *
- * Note 1:
- *	To guarantee log10(10**n)=n, where 10**n is normal, the rounding 
- *	mode must set to Round-to-Nearest.
- * Note 2:
- *	[1/log(10)] rounded to 53 bits has error  .198   ulps;
- *	log10 is monotonic at all binary break points.
- *
- * Special cases:
- *	log10(x) is NaN with signal if x < 0; 
- *	log10(+INF) is +INF with no signal; log10(0) is -INF with signal;
- *	log10(NaN) is that NaN with no signal;
- *	log10(10**N) = N  for N=0,1,...,22.
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following constants.
- * The decimal values may be used, provided that the compiler will convert
- * from decimal to binary accurately enough to produce the hexadecimal values
- * shown.

- *
- * Special cases:
- *	1.  (anything) ** 0  is 1
- *	2.  (anything) ** 1  is itself
- *	3.  (anything) ** NAN is NAN
- *	4.  NAN ** (anything except 0) is NAN

- *
- * Accuracy:

-/* __ieee754_sqrt(x)
- * Return correctly rounded sqrt.
- *           ------------------------------------------
- *	     |  Use the hardware sqrt if you have one |
- *           ------------------------------------------
- * Method: 
- *   Bit by bit method using integer arithmetic. (Slow, but portable) 
- *   1. Normalization
- *	Scale x to y in [1,4) with even powers of 2: 
- *	find an integer k such that  1 <= (y=x*2^(2k)) < 4, then
- *		sqrt(x) = 2^k * sqrt(y)
- *   2. Bit by bit computation
- *	Let q  = sqrt(y) truncated to i bit after binary point (q = 1),
- *	     i							 0
- *                                     i+1         2
- *	    s  = 2*q , and	y  =  2   * ( y - q  ).		(1)
- *	     i      i            i                 i
- *                                                        
- *	To compute q    from q , one checks whether 
- *		    i+1       i                       
- *
- *			      -(i+1) 2
- *			(q + 2      ) <= y.			(2)
- *     			  i
- *							      -(i+1)
- *	If (2) is false, then q   = q ; otherwise q   = q  + 2      .
- *		 	       i+1   i             i+1   i
- *
- *	With some algebric manipulation, it is not difficult to see
- *	that (2) is equivalent to 
- *                             -(i+1)
- *			s  +  2       <= y			(3)
- *			 i                i
- *
- *	The advantage of (3) is that s  and y  can be computed by 
- *				      i      i
- *	the following recurrence formula:
- *	    if (3) is false
- *
- *	    s     =  s  ,	y    = y   ;			(4)
- *	     i+1      i		 i+1    i
- *
- *	    otherwise,
- *                         -i                     -(i+1)
- *	    s	  =  s  + 2  ,  y    = y  -  s  - 2  		(5)
- *           i+1      i          i+1    i     i
- *				
- *	One may easily use induction to prove (4) and (5). 
- *	Note. Since the left hand side of (3) contain only i+2 bits,
- *	      it does not necessary to do a full (53-bit) comparison 
- *	      in (3).
- *   3. Final rounding
- *	After generating the 53 bits result, we compute one more bit.
- *	Together with the remainder, we can decide whether the
- *	result is exact, bigger than 1/2ulp, or less than 1/2ulp
- *	(it will never equal to 1/2ulp).
- *	The rounding mode can be detected by checking whether
- *	huge + tiny is equal to huge, and whether huge - tiny is
- *	equal to huge for some floating point number "huge" and "tiny".
- *		
- * Special cases:
- *	sqrt(+-0) = +-0 	... exact
- *	sqrt(inf) = inf
- *	sqrt(-ve) = NaN		... with invalid signal
- *	sqrt(NaN) = NaN		... with invalid signal for signaling NaN
- *
- * Other methods : see the appended file at the end of the program below.

-Other methods  (use floating-point arithmetic)
--------------
-(This is a copy of a drafted paper by Prof W. Kahan 
-and K.C. Ng, written in May, 1986)
-
-	Two algorithms are given here to implement sqrt(x) 
-	(IEEE double precision arithmetic) in software.
-	Both supply sqrt(x) correctly rounded. The first algorithm (in
-	Section A) uses newton iterations and involves four divisions.
-	The second one uses reciproot iterations to avoid division, but
-	requires more multiplications. Both algorithms need the ability
-	to chop results of arithmetic operations instead of round them, 
-	and the INEXACT flag to indicate when an arithmetic operation
-	is executed exactly with no roundoff error, all part of the 
-	standard (IEEE 754-1985). The ability to perform shift, add,
-	subtract and logical AND operations upon 32-bit words is needed
-	too, though not part of the standard.
-
-A.  sqrt(x) by Newton Iteration
-
-   (1)	Initial approximation
-
-	Let x0 and x1 be the leading and the trailing 32-bit words of
-	a floating point number x (in IEEE double format) respectively 
-
-	    1    11		     52				  ...widths
-	   ------------------------------------------------------
-	x: |s|	  e     |	      f				|
-	   ------------------------------------------------------
-	      msb    lsb  msb				      lsb ...order
-
- 
-	     ------------------------  	     ------------------------
-	x0:  |s|   e    |    f1     |	 x1: |          f2           |
-	     ------------------------  	     ------------------------
-
-	By performing shifts and subtracts on x0 and x1 (both regarded
-	as integers), we obtain an 8-bit approximation of sqrt(x) as
-	follows.
-
-		k  := (x0>>1) + 0x1ff80000;
-		y0 := k - T1[31&(k>>15)].	... y ~ sqrt(x) to 8 bits
-	Here k is a 32-bit integer and T1[] is an integer array containing
-	correction terms. Now magically the floating value of y (y's
-	leading 32-bit word is y0, the value of its trailing word is 0)
-	approximates sqrt(x) to almost 8-bit.
-
-	Value of T1:
-	static int T1[32]= {
-	0,	1024,	3062,	5746,	9193,	13348,	18162,	23592,
-	29598,	36145,	43202,	50740,	58733,	67158,	75992,	85215,
-	83599,	71378,	60428,	50647,	41945,	34246,	27478,	21581,
-	16499,	12183,	8588,	5674,	3403,	1742,	661,	130,};
-
-    (2)	Iterative refinement
-
-	Apply Heron's rule three times to y, we have y approximates 
-	sqrt(x) to within 1 ulp (Unit in the Last Place):
-
-		y := (y+x/y)/2		... almost 17 sig. bits
-		y := (y+x/y)/2		... almost 35 sig. bits
-		y := y-(y-x/y)/2	... within 1 ulp
-
-
-	Remark 1.
-	    Another way to improve y to within 1 ulp is:
-
-		y := (y+x/y)		... almost 17 sig. bits to 2*sqrt(x)
-		y := y - 0x00100006	... almost 18 sig. bits to sqrt(x)
-
-				2
-			    (x-y )*y
-		y := y + 2* ----------	...within 1 ulp
-			       2
-			     3y  + x
-
-
-	This formula has one division fewer than the one above; however,
-	it requires more multiplications and additions. Also x must be
-	scaled in advance to avoid spurious overflow in evaluating the
-	expression 3y*y+x. Hence it is not recommended uless division
-	is slow. If division is very slow, then one should use the 
-	reciproot algorithm given in section B.
-
-    (3) Final adjustment
-
-	By twiddling y's last bit it is possible to force y to be 
-	correctly rounded according to the prevailing rounding mode
-	as follows. Let r and i be copies of the rounding mode and
-	inexact flag before entering the square root program. Also we
-	use the expression y+-ulp for the next representable floating
-	numbers (up and down) of y. Note that y+-ulp = either fixed
-	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
-	mode.
-
-		I := FALSE;	... reset INEXACT flag I
-		R := RZ;	... set rounding mode to round-toward-zero
-		z := x/y;	... chopped quotient, possibly inexact
-		If(not I) then {	... if the quotient is exact
-		    if(z=y) {
-		        I := i;	 ... restore inexact flag
-		        R := r;  ... restore rounded mode
-		        return sqrt(x):=y.
-		    } else {
-			z := z - ulp;	... special rounding
-		    }
-		}
-		i := TRUE;		... sqrt(x) is inexact
-		If (r=RN) then z=z+ulp	... rounded-to-nearest
-		If (r=RP) then {	... round-toward-+inf
-		    y = y+ulp; z=z+ulp;
-		}
-		y := y+z;		... chopped sum
-		y0:=y0-0x00100000;	... y := y/2 is correctly rounded.
-	        I := i;	 		... restore inexact flag
-	        R := r;  		... restore rounded mode
-	        return sqrt(x):=y.
-		    
-    (4)	Special cases
-
-	Square root of +inf, +-0, or NaN is itself;
-	Square root of a negative number is NaN with invalid signal.
-
-
-B.  sqrt(x) by Reciproot Iteration
-
-   (1)	Initial approximation
-
-	Let x0 and x1 be the leading and the trailing 32-bit words of
-	a floating point number x (in IEEE double format) respectively
-	(see section A). By performing shifs and subtracts on x0 and y0,
-	we obtain a 7.8-bit approximation of 1/sqrt(x) as follows.
-
-	    k := 0x5fe80000 - (x0>>1);
-	    y0:= k - T2[63&(k>>14)].	... y ~ 1/sqrt(x) to 7.8 bits
-
-	Here k is a 32-bit integer and T2[] is an integer array 
-	containing correction terms. Now magically the floating
-	value of y (y's leading 32-bit word is y0, the value of
-	its trailing word y1 is set to zero) approximates 1/sqrt(x)
-	to almost 7.8-bit.
-
-	Value of T2:
-	static int T2[64]= {
-	0x1500,	0x2ef8,	0x4d67,	0x6b02,	0x87be,	0xa395,	0xbe7a,	0xd866,
-	0xf14a,	0x1091b,0x11fcd,0x13552,0x14999,0x15c98,0x16e34,0x17e5f,
-	0x18d03,0x19a01,0x1a545,0x1ae8a,0x1b5c4,0x1bb01,0x1bfde,0x1c28d,
-	0x1c2de,0x1c0db,0x1ba73,0x1b11c,0x1a4b5,0x1953d,0x18266,0x16be0,
-	0x1683e,0x179d8,0x18a4d,0x19992,0x1a789,0x1b445,0x1bf61,0x1c989,
-	0x1d16d,0x1d77b,0x1dddf,0x1e2ad,0x1e5bf,0x1e6e8,0x1e654,0x1e3cd,
-	0x1df2a,0x1d635,0x1cb16,0x1be2c,0x1ae4e,0x19bde,0x1868e,0x16e2e,
-	0x1527f,0x1334a,0x11051,0xe951,	0xbe01,	0x8e0d,	0x5924,	0x1edd,};
-
-    (2)	Iterative refinement
-
-	Apply Reciproot iteration three times to y and multiply the
-	result by x to get an approximation z that matches sqrt(x)
-	to about 1 ulp. To be exact, we will have 
-		-1ulp < sqrt(x)-z<1.0625ulp.
-	
-	... set rounding mode to Round-to-nearest
-	   y := y*(1.5-0.5*x*y*y)	... almost 15 sig. bits to 1/sqrt(x)
-	   y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/sqrt(x)
-	... special arrangement for better accuracy
-	   z := x*y			... 29 bits to sqrt(x), with z*y<1
-	   z := z + 0.5*z*(1-z*y)	... about 1 ulp to sqrt(x)
-
-	Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
-	(a) the term z*y in the final iteration is always less than 1; 
-	(b) the error in the final result is biased upward so that
-		-1 ulp < sqrt(x) - z < 1.0625 ulp
-	    instead of |sqrt(x)-z|<1.03125ulp.
-
-    (3)	Final adjustment
-
-	By twiddling y's last bit it is possible to force y to be 
-	correctly rounded according to the prevailing rounding mode
-	as follows. Let r and i be copies of the rounding mode and
-	inexact flag before entering the square root program. Also we
-	use the expression y+-ulp for the next representable floating
-	numbers (up and down) of y. Note that y+-ulp = either fixed
-	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
-	mode.
-
-	R := RZ;		... set rounding mode to round-toward-zero
-	switch(r) {
-	    case RN:		... round-to-nearest
-	       if(x<= z*(z-ulp)...chopped) z = z - ulp; else
-	       if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;
-	       break;
-	    case RZ:case RM:	... round-to-zero or round-to--inf
-	       R:=RP;		... reset rounding mod to round-to-+inf
-	       if(x<z*z ... rounded up) z = z - ulp; else
-	       if(x>=(z+ulp)*(z+ulp) ...rounded up) z = z+ulp;
-	       break;
-	    case RP:		... round-to-+inf
-	       if(x>(z+ulp)*(z+ulp)...chopped) z = z+2*ulp; else
-	       if(x>z*z ...chopped) z = z+ulp;
-	       break;
-	}
-
-	Remark 3. The above comparisons can be done in fixed point. For
-	example, to compare x and w=z*z chopped, it suffices to compare
-	x1 and w1 (the trailing parts of x and w), regarding them as
-	two's complement integers.
-
-	...Is z an exact square root?
-	To determine whether z is an exact square root of x, let z1 be the
-	trailing part of z, and also let x0 and x1 be the leading and
-	trailing parts of x.
-
-	If ((z1&0x03ffffff)!=0)	... not exact if trailing 26 bits of z!=0
-	    I := 1;		... Raise Inexact flag: z is not exact
-	else {
-	    j := 1 - [(x0>>20)&1]	... j = logb(x) mod 2
-	    k := z1 >> 26;		... get z's 25-th and 26-th 
-					    fraction bits
-	    I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
-	}
-	R:= r		... restore rounded mode
-	return sqrt(x):=z.
-
-	If multiplication is cheaper then the foregoing red tape, the 
-	Inexact flag can be evaluated by
-
-	    I := i;
-	    I := (z*z!=x) or I.
-
-	Note that z*z can overwrite I; this value must be sensed if it is 
-	True.
-
-	Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
-	zero.
-
-		    --------------------
-		z1: |        f2        | 
-		    --------------------
-		bit 31		   bit 0
-
-	Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
-	or even of logb(x) have the following relations:
-
-	-------------------------------------------------
-	bit 27,26 of z1		bit 1,0 of x1	logb(x)
-	-------------------------------------------------
-	00			00		odd and even
-	01			01		even
-	10			10		odd
-	10			00		even
-	11			01		even
-	-------------------------------------------------
-
-    (4)	Special cases (see (4) of Section A).

- *			x[i] = floor(z)
- *			z    = (z-x[i])*2**24
- *
- *
- *	y[]	ouput result in an array of double precision numbers.
- *		The dimension of y[] is:
- *			24-bit  precision	1
- *			53-bit  precision	2
- *			64-bit  precision	2
- *			113-bit precision	3
- *		The actual value is the sum of them. Thus for 113-bit
- *		precison, one may have to do something like:
- *
- *		long double t,w,r_head, r_tail;
- *		t = (long double)y[2] + (long double)y[1];
- *		w = (long double)y[0];
- *		r_head = t+w;
- *		r_tail = w - (r_head - t);
- *
- *	e0	The exponent of x[0]
- *
- *	nx	dimension of x[]
- *
- *  	prec	an integer indicating the precision:
- *			0	24  bits (single)
- *			1	53  bits (double)
- *			2	64  bits (extended)
- *			3	113 bits (quad)
- *
- *	ipio2[]
- *		integer array, contains the (24*i)-th to (24*i+23)-th 
- *		bit of 2/pi after binary point. The corresponding 
- *		floating value is
- *
- *			ipio2[i] * 2^(-24(i+1)).
- *
- * External function:
- *	double scalbn(), floor();
- *
- *
- * Here is the description of some local variables:
- *
- * 	jk	jk+1 is the initial number of terms of ipio2[] needed
- *		in the computation. The recommended value is 2,3,4,
- *		6 for single, double, extended,and quad.
- *
- * 	jz	local integer variable indicating the number of 
- *		terms of ipio2[] used. 
- *
- *	jx	nx - 1
- *
- *	jv	index for pointing to the suitable ipio2[] for the
- *		computation. In general, we want
- *			( 2^e0*x[0] * ipio2[jv-1]*2^(-24jv) )/8
- *		is an integer. Thus
- *			e0-3-24*jv >= 0 or (e0-3)/24 >= jv
- *		Hence jv = max(0,(e0-3)/24).
- *
- *	jp	jp+1 is the number of terms in PIo2[] needed, jp = jk.
- *
- * 	q[]	double array with integral value, representing the
- *		24-bits chunk of the product of x and 2/pi.
- *
- *	q0	the corresponding exponent of q[0]. Note that the
- *		exponent for q[i] would be q0-24*i.
- *
- *	PIo2[]	double precision array, obtained by cutting pi/2
- *		into 24 bits chunks. 
- *
- *	f[]	ipio2[] in floating point 
- *
- *	iq[]	integer array by breaking up q[] in 24-bits chunk.
- *
- *	fq[]	final product of x*(2/pi) in fq[0],..,fq[jk]
- *
- *	ih	integer. If >0 it indicates q[] is >= 0.5, hence
- *		it also indicates the *sign* of the result.

-/* __kernel_tan( x, y, k )
- * kernel tan function on [-pi/4, pi/4], pi/4 ~ 0.7854
- * Input x is assumed to be bounded by ~pi/4 in magnitude.
- * Input y is the tail of x.
- * Input k indicates whether tan (if k=1) or 
- * -1/tan (if k= -1) is returned.
- *
- * Algorithm
- *	1. Since tan(-x) = -tan(x), we need only to consider positive x. 
- *	2. if x < 2^-28 (hx<0x3e300000 0), return x with inexact if x!=0.
- *	3. tan(x) is approximated by a odd polynomial of degree 27 on
- *	   [0,0.67434]
- *		  	         3             27
- *	   	tan(x) ~ x + T1*x + ... + T13*x
- *	   where
- *	
- * 	        |tan(x)         2     4            26   |     -59.2
- * 	        |----- - (1+T1*x +T2*x +.... +T13*x    )| <= 2
- * 	        |  x 					| 
- * 
- *	   Note: tan(x+y) = tan(x) + tan'(x)*y
- *		          ~ tan(x) + (1+x*x)*y
- *	   Therefore, for better accuracy in computing tan(x+y), let 
- *		     3      2      2       2       2
- *		r = x *(T2+x *(T3+x *(...+x *(T12+x *T13))))
- *	   then
- *		 		    3    2
- *		tan(x+y) = x + (T1*x + (x *(r+y)+y))
- *
- *      4. For x in [0.67434,pi/4],  let y = pi/4 - x, then
- *		tan(x) = tan(pi/4-y) = (1-tan(y))/(1+tan(y))
- *		       = 1 - 2*(tan(y) - (tan(y)^2)/(1+tan(y)))

-/* atan(x)
- * Method
- *   1. Reduce x to positive by atan(x) = -atan(-x).
- *   2. According to the integer k=4t+0.25 chopped, t=x, the argument
- *      is further reduced to one of the following intervals and the
- *      arctangent of t is evaluated by the corresponding formula:
- *
- *      [0,7/16]      atan(x) = t-t^3*(a1+t^2*(a2+...(a10+t^2*a11)...)
- *      [7/16,11/16]  atan(x) = atan(1/2) + atan( (t-0.5)/(1+t/2) )
- *      [11/16.19/16] atan(x) = atan( 1 ) + atan( (t-1)/(1+t) )
- *      [19/16,39/16] atan(x) = atan(3/2) + atan( (t-1.5)/(1+1.5t) )
- *      [39/16,INF]   atan(x) = atan(INF) + atan( -1/t )
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough 
- * to produce the hexadecimal values shown.

- * double erfc(double x)
- *			     x
- *		      2      |\
- *     erf(x)  =  ---------  | exp(-t*t)dt
- *	 	   sqrt(pi) \| 
- *			     0
- *
- *     erfc(x) =  1-erf(x)
- *  Note that 
- *		erf(-x) = -erf(x)
- *		erfc(-x) = 2 - erfc(x)
- *
- * Method:
- *	1. For |x| in [0, 0.84375]
- *	    erf(x)  = x + x*R(x^2)
- *          erfc(x) = 1 - erf(x)           if x in [-.84375,0.25]
- *                  = 0.5 + ((0.5-x)-x*R)  if x in [0.25,0.84375]
- *	   where R = P/Q where P is an odd poly of degree 8 and
- *	   Q is an odd poly of degree 10.
- *						 -57.90
- *			| R - (erf(x)-x)/x | <= 2
- *	
- *
- *	   Remark. The formula is derived by noting
- *          erf(x) = (2/sqrt(pi))*(x - x^3/3 + x^5/10 - x^7/42 + ....)
- *	   and that
- *          2/sqrt(pi) = 1.128379167095512573896158903121545171688
- *	   is close to one. The interval is chosen because the fix
- *	   point of erf(x) is near 0.6174 (i.e., erf(x)=x when x is
- *	   near 0.6174), and by some experiment, 0.84375 is chosen to
- * 	   guarantee the error is less than one ulp for erf.
- *
- *      2. For |x| in [0.84375,1.25], let s = |x| - 1, and
- *         c = 0.84506291151 rounded to single (24 bits)
- *         	erf(x)  = sign(x) * (c  + P1(s)/Q1(s))
- *         	erfc(x) = (1-c)  - P1(s)/Q1(s) if x > 0
- *			  1+(c+P1(s)/Q1(s))    if x < 0
- *         	|P1/Q1 - (erf(|x|)-c)| <= 2**-59.06
- *	   Remark: here we use the taylor series expansion at x=1.
- *		erf(1+s) = erf(1) + s*Poly(s)
- *			 = 0.845.. + P1(s)/Q1(s)
- *	   That is, we use rational approximation to approximate
- *			erf(1+s) - (c = (single)0.84506291151)
- *	   Note that |P1/Q1|< 0.078 for x in [0.84375,1.25]
- *	   where 
- *		P1(s) = degree 6 poly in s
- *		Q1(s) = degree 6 poly in s
- *
- *      3. For x in [1.25,1/0.35(~2.857143)], 
- *         	erfc(x) = (1/x)*exp(-x*x-0.5625+R1/S1)
- *         	erf(x)  = 1 - erfc(x)
- *	   where 
- *		R1(z) = degree 7 poly in z, (z=1/x^2)
- *		S1(z) = degree 8 poly in z
- *
- *      4. For x in [1/0.35,28]
- *         	erfc(x) = (1/x)*exp(-x*x-0.5625+R2/S2) if x > 0
- *			= 2.0 - (1/x)*exp(-x*x-0.5625+R2/S2) if -6<x<0
- *			= 2.0 - tiny		(if x <= -6)
- *         	erf(x)  = sign(x)*(1.0 - erfc(x)) if x < 6, else
- *         	erf(x)  = sign(x)*(1.0 - tiny)
- *	   where
- *		R2(z) = degree 6 poly in z, (z=1/x^2)
- *		S2(z) = degree 7 poly in z
- *
- *      Note1:
- *	   To compute exp(-x*x-0.5625+R/S), let s be a single
- *	   precision number and s := x; then
- *		-x*x = -s*s + (s-x)*(s+x)
- *	        exp(-x*x-0.5626+R/S) = 
- *			exp(-s*s-0.5625)*exp((s-x)*(s+x)+R/S);
- *      Note2:
- *	   Here 4 and 5 make use of the asymptotic series
- *			  exp(-x*x)
- *		erfc(x) ~ ---------- * ( 1 + Poly(1/x^2) )
- *			  x*sqrt(pi)
- *	   We use rational approximation to approximate
- *      	g(s)=f(1/x^2) = log(erfc(x)*x) - x*x + 0.5625
- *	   Here is the error bound for R1/S1 and R2/S2
- *      	|R1/S1 - f(x)|  < 2**(-62.57)
- *      	|R2/S2 - f(x)|  < 2**(-61.52)
- *
- *      5. For inf > x >= 28
- *         	erf(x)  = sign(x) *(1 - tiny)  (raise inexact)
- *         	erfc(x) = tiny*tiny (raise underflow) if x > 0
- *			= 2 - tiny if x<0
- *
- *      7. Special case:
- *         	erf(0)  = 0, erf(inf)  = 1, erf(-inf) = -1,
- *         	erfc(0) = 1, erfc(inf) = 0, erfc(-inf) = 2, 
- *	   	erfc/erf(NaN) is NaN

-/* expm1(x)
- * Returns exp(x)-1, the exponential of x minus 1.
- *
- * Method
- *   1. Argument reduction:
- *	Given x, find r and integer k such that
- *
- *               x = k*ln2 + r,  |r| <= 0.5*ln2 ~ 0.34658  
- *
- *      Here a correction term c will be computed to compensate 
- *	the error in r when rounded to a floating-point number.
- *
- *   2. Approximating expm1(r) by a special rational function on
- *	the interval [0,0.34658]:
- *	Since
- *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
- *	we define R1(r*r) by
- *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
- *	That is,
- *	    R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
- *		     = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
- *		     = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
- *      We use a special Reme algorithm on [0,0.347] to generate 
- * 	a polynomial of degree 5 in r*r to approximate R1. The 
- *	maximum error of this polynomial approximation is bounded 
- *	by 2**-61. In other words,
- *	    R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
- *	where 	Q1  =  -1.6666666666666567384E-2,
- * 		Q2  =   3.9682539681370365873E-4,
- * 		Q3  =  -9.9206344733435987357E-6,
- * 		Q4  =   2.5051361420808517002E-7,
- * 		Q5  =  -6.2843505682382617102E-9;
- *  	(where z=r*r, and the values of Q1 to Q5 are listed below)
- *	with error bounded by
- *	    |                  5           |     -61
- *	    | 1.0+Q1*z+...+Q5*z   -  R1(z) | <= 2 
- *	    |                              |
- *	
- *	expm1(r) = exp(r)-1 is then computed by the following 
- * 	specific way which minimize the accumulation rounding error: 
- *			       2     3
- *			      r     r    [ 3 - (R1 + R1*r/2)  ]
- *	      expm1(r) = r + --- + --- * [--------------------]
- *		              2     2    [ 6 - r*(3 - R1*r/2) ]
- *	
- *	To compensate the error in the argument reduction, we use
- *		expm1(r+c) = expm1(r) + c + expm1(r)*c 
- *			   ~ expm1(r) + c + r*c 
- *	Thus c+r*c will be added in as the correction terms for
- *	expm1(r+c). Now rearrange the term to avoid optimization 
- * 	screw up:
- *		        (      2                                    2 )
- *		        ({  ( r    [ R1 -  (3 - R1*r/2) ]  )  }    r  )
- *	 expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
- *	                ({  ( 2    [ 6 - r*(3 - R1*r/2) ]  )  }    2  )
- *                      (                                             )
- *    	
- *		   = r - E
- *   3. Scale back to obtain expm1(x):
- *	From step 1, we have
- *	   expm1(x) = either 2^k*[expm1(r)+1] - 1
- *		    = or     2^k*[expm1(r) + (1-2^-k)]
- *   4. Implementation notes:
- *	(A). To save one multiplication, we scale the coefficient Qi
- *	     to Qi*2^i, and replace z by (x^2)/2.
- *	(B). To achieve maximum accuracy, we compute expm1(x) by
- *	  (i)   if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
- *	  (ii)  if k=0, return r-E
- *	  (iii) if k=-1, return 0.5*(r-E)-0.5
- *        (iv)	if k=1 if r < -0.25, return 2*((r+0.5)- E)
- *	       	       else	     return  1.0+2.0*(r-E);
- *	  (v)   if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
- *	  (vi)  if k <= 20, return 2^k((1-2^-k)-(E-r)), else
- *	  (vii) return 2^k(1-((E+2^-k)-r)) 
- *
- * Special cases:
- *	expm1(INF) is INF, expm1(NaN) is NaN;
- *	expm1(-INF) is -1, and
- *	for finite argument, only expm1(0)=0 is exact.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Misc. info.
- *	For IEEE double 
- *	    if x >  7.09782712893383973096e+02 then expm1(x) overflow
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough
- * to produce the hexadecimal values shown.

-/* double log1p(double x)
- *
- * Method :                  
- *   1. Argument Reduction: find k and f such that 
- *			1+x = 2^k * (1+f), 
- *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
- *
- *      Note. If k=0, then f=x is exact. However, if k!=0, then f
- *	may not be representable exactly. In that case, a correction
- *	term is need. Let u=1+x rounded. Let c = (1+x)-u, then
- *	log(1+x) - log(u) ~ c/u. Thus, we proceed to compute log(u),
- *	and add back the correction term c/u.
- *	(Note: when x > 2**53, one can simply return log(x))
- *
- *   2. Approximation of log1p(f).
- *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
- *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- *	     	 = 2s + s*R
- *      We use a special Reme algorithm on [0,0.1716] to generate 
- * 	a polynomial of degree 14 to approximate R The maximum error 
- *	of this polynomial approximation is bounded by 2**-58.45. In
- *	other words,
- *		        2      4      6      8      10      12      14
- *	    R(z) ~ Lp1*s +Lp2*s +Lp3*s +Lp4*s +Lp5*s  +Lp6*s  +Lp7*s
- *  	(the values of Lp1 to Lp7 are listed in the program)
- *	and
- *	    |      2          14          |     -58.45
- *	    | Lp1*s +...+Lp7*s    -  R(z) | <= 2 
- *	    |                             |
- *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
- *	In order to guarantee error in log below 1ulp, we compute log
- *	by
- *		log1p(f) = f - (hfsq - s*(hfsq+R)).
- *	
- *	3. Finally, log1p(x) = k*ln2 + log1p(f).  
- *		 	     = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
- *	   Here ln2 is split into two floating point number: 
- *			ln2_hi + ln2_lo,
- *	   where n*ln2_hi is always exact for |n| < 2000.
- *
- * Special cases:
- *	log1p(x) is NaN with signal if x < -1 (including -INF) ; 
- *	log1p(+INF) is +INF; log1p(-1) is -INF with signal;
- *	log1p(NaN) is that NaN with no signal.
- *
- * Accuracy:
- *	according to an error analysis, the error is always less than
- *	1 ulp (unit in the last place).
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough 
- * to produce the hexadecimal values shown.
- *
- * Note: Assuming log() return accurate answer, the following
- * 	 algorithm can be used to compute log1p(x) to within a few ULP:
- *	
- *		u = 1+x;
- *		if(u==1.0) return x ; else
- *			   return log(u)*(x/(u-1.0));
- *
- *	 See HP-15C Advanced Functions Handbook, p.193.
