Why hypot() function is so slow?
It’s not a simple sqrt function. You should check this link for the implementation of the algorithm: http://www.koders.com/c/fid7D3C8841ADC384A5F8DE0D081C88331E3909BF3A.aspx It has while loop to check for convergence /* Slower but safer algorithm due to Moler and Morrison. Never produces any intermediate result greater than roughly the larger of X and Y. Should converge to machine-precision accuracy … Read more
