SYNOPSIS | |
float atan2(int|float y, int|float x) | |
DESCRIPTION | |
Returns the angle part of the polar coordinates of the point (x, y) | |
in the range (-pi, pi]. | |
Note the exchange of the coordinates x and y in the parameter list | |
reflecting the sequenz in the gradient to angle transformation | |
atan(y / x). | |
