|Property/method value type:||Number primitive|
|Argument list:||aValue1||Some meaningful numeric value|
|aValue2||Some meaningful numeric value|
This function computes the quotient of arg2/arg1 and then returns the arc tangent of the result. It takes into account which quadrant the value falls into according to the signs of the two arguments.
Traditionally, for this function, the Y argument is placed first and the X argument second.
Special boundary conditions that affect the results are:
|0||negative||pi * sign of Argument1|
The exact value yielded by this function may vary slightly from implementation to implementation due to differences in the underlying precision of the implementations math routines and the specific algorithm selected to evaluate this function.
The result of this method is the arc-tangent of the slope of the two arguments. The result is expressed in radians and ranges from -pi to +pi.
