| 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). | |
| HISTORY | |
| LDMud 3.2.9 added integers as arguments. | |
