It computes the arc tangent of y/x and calculates the angle in radians to determine the correct quadrant. double atan2( double y, double x ); If the argument has type int or the type double, atan2 is called. float atan2f( float y, float x ); Returns the arctangent, or inverse tangent, of the specified x- and y-coordinates.

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 result is an angle expressed in radians. To convert from radians to …
Returns the arctangent, or inverse tangent, of the specified x- and y-coordinates. The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates (x_num, y_num). The following vectorizes: doublea[32],b[32],c[32]; for (int i = 0 ; i c = atan2(a ,b ); } and the following does not (mixed data types)
