ECMA Section: 15.7.1 The Number Constructor Called as a Function
|
|
15.7.1.1
|
|
15.7.1.2
|
|
|
|
Description: When Number is called as a function rather than as a
|
|
constructor, it performs a type conversion.
|
|
15.7.1.1 Return a number value (not a Number object)
|
|
computed by ToNumber( value )
|
|
15.7.1.2 Number() returns 0.
|
|
|
|
need to add more test cases. see the testcases for
|
|
TypeConversion ToNumber.
