WebFunction atan2() takes two arguments: x-coordinate and y-coordinate, and calculate the angle in radians for the quadrant. For better understanding of atan2(): [Mathematics] tan-1 (y/x) = atan2(y,x) [In C programming] Two other functions atan2f() and atan2l() are also present in C to specifically work with float and long double respectively. 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.
