Optimizations for pow() with const non-integer exponent? http://stackoverflow.com/questions/6475373/optimizations-for-pow-with-const-non-integer-exponent On SSE the relevant instructions are cvtdq2ps and cvtps2dq . It's not quite so simple though. The exponent field in IEEE.. x^p exp2 p log2 x exp2 p log2 x 127 127 127 127 cvtps2dq p log2 x 127 127 127 p cvtps2dq p log2 x 127 log2 exp2 127 127.. p log2 x 127 127 127 127 cvtps2dq p log2 x 127 127 127 p cvtps2dq p log2 x 127 log2 exp2 127 127 p cvtps2dq p log2 x exp2 127..
