|
* SUMMARY: Testing the |atan2()| method for the Math object. The method
|
|
* returns a numeric value between -pi and pi representing the angle theta of
|
|
* an (x,y) point. This is the counterclockwise angle, measured in radians,
|
|
* between the positive X axis, and the point (x,y). Note that the arguments
|
|
* to this function pass the y-coordinate first and the x-coordinate second.
|
|
* |atan2()| is passed separate x and y arguments, and |atan2()| is passed the
|
|
* ratio of those two arguments. Because |atan2()| is a static method of Math,
|
|
* you always use it as |Math.atan2()|, rather than as a method of a Math
|
|
* object you created.
|
|
*
|
|
* Syntax: |atan2(x)| where x is a number.
