Comment on Speeding up atan2fparentComments−stephencanon5yThanks for clarifying!Without benchmarking, I would expect atan2f to be around 20-30 cycles per element or less with either Intel's or Apple's scalar math library, and proportionally faster for their vector libs.−rostayobOP5yThanks for the info.By the way, your writing on floating point arithmetic is very informative -- I even cite a message of yours on FMA in the post itself!
