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.
