WebFaster atan2? Python 2.7 on RaspberryPi (ARM). Currently in my program the bottleneck is computing atan2 over ~240k datapoints. I've tried programming a function to approximate: def pseudoangle (dx, dy): ax = abs (dx) ay = abs (dy) p = dy/ (ax+ay) if dx < 0: p = 2 - p # elif dy < 0: p = 4 + p return p. This however is much slower than the built ... WebUse Fast Park and take a shortcut through the world's busiest airport.*.
