WebAug 21, 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.

Computing Arc tangent only using the ratio y/x is not enough to determine the angle since there is an indeterminacy. Opposite quadrants are giving the same ratio. ArcTan2 is not using y/x to compute the angle but y and x and use the sign of y and x to determine the quadrant. hockey bedding full https://elyondigital.com
