Inverse tangens of Y/X.

Pascal
function ArcTan2(const Y: TMtxVec; const X: TMtxVec): TMtxVec; overload;
Description

Calculates the inverse tangens of Y/X, and returns an angle in the correct quadrant. The results are stored in calling object elements. Size and Complex properties of calling object are adjusted automatically to match those of X and Y objects. An exception is raised if X and Y size and Complex properties do not match. 

Note that ArcTan is calculated as ArcTan2(1, X).
