Which is the same as "just add 2 * PI" if you're having one of those days. Or if you don't like branching, negate the two parameters and add 180° to the answer. (Adding 180° to the return value puts it nicely in the 0-360 range, but flips the angle.

Math.Atan2 () is an inbuilt Math class method which returns the angle whose tangent is the quotient of two specified numbers. Basically, it returns an angle θ (measured in radian) whose value lies between -π and π. This is a counterclockwise angle lies between the positive x-axis, and the point (x, y).
