Web21 ago 2009 · Add 360° if the answer from atan2 is less than 0°. 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.
