NAME
+
       atan2 - arc tangent function of two variables
+
+
SYNOPSIS
+
       #include <math.h>
+
+       double atan2(double y, double x);
+
+
DESCRIPTION
+
       The atan2() function calculates the arc tangent of the two
+       variables x and y.  It is similar to calculating  the  arc
+       tangent  of y / x, except that the signs of both arguments
+       are used to determine the quadrant of the result.
+
+
RETURN VALUE
+
       The atan2() function returns the result in radians,  which
+       is between -PI and PI (inclusive).
