Ohhh yeah, thanks for the tip. I have to check if SSE instructions have diferent times for * / operators...WhiteNoise wrote:x - 1/6 * x * x * x. Multiplying by 1/6 might be faster than dividing by 6..? Worth a try.-Dave

yeah, ultimately the best hand-coded assembly will beat the best optimized code, but presumably it's all a matter of opportunity costs -- is it worth the time required to try to squeeze an extra 1% out (which you might not even get)? depends on every application, i suppose.
as for * an / -- surely multiplication is always faster than division (by a degree of magnitude at that, i would think)?
