atan2 − arc tangent function of two variables
#include <math.h>
double atan2(double y, double x);
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.
The atan2() function returns the result in radians, which is between -PI and PI (inclusive).
