If the above approximation for pow is not good enough, you can still try to replace it with exponential functions, depending on your machine and compiler this might be faster: x^y = e^ (y*ln (x)) And the result: e^ (z * x^y) = e^ (z * e^ (y*ln (x))) Another trick is when some parameters of the formula do not change often. gumtree midlothian scotland

WebJul 25, 2014 · Random floats will rarely be integers. So it's really down to your particular use for exponentiation. Without evidence that people are feeding some relatively large percentage of ints into the exponent, it's just extra code and extra time. – Nosredna Jun 19, 2009 at 20:35 Show 2 more comments 4 WebIt is fast but result can be quite a bit off, since we directly mess with the floating point exponent.-> use it only for getting rough estimates of the values and where precision is not that important. fastroot (f,n) gives the n-th root of f.
