Atan2 c++ 使い方
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. WebOct 11, 2024 · Solution: This problem is solved by atan2. It requires both the y and the x separately and therefore can keep the distinction e.g. between 2 positive and 2 negatives etc. In order to use it supply it with the 2 arguments, e.g.: theta = atan2 (*b, *a);
