WebMar 26, 2024 · This is a fixed point version of the libc atan2() routine. It computes the arc tangent of y / x, but the signs of both arguments are used to determine the quadrant of the result, and x is permitted to be zero. This function is useful to convert Cartesian coordinates to polar coordinates. Example: WebI made a function to compute a fixed-point approximation of atan2 (y, x). The problem is that of the ~83 cycles it takes to run the whole function, 70 cycles (compiling with gcc … lichess tournaments
