What exactly is an 'aligned pointer'?

http://stackoverflow.com/questions/4322926/what-exactly-is-an-aligned-pointer

in binary an address aligned to n bytes will have its log2 n least significant bits set to zero. For instance an object.. properly aligned address that ends with binary 00000 since log2 32 is 5. This also implies that an address can be forced into..

Optimizations for pow() with const non-integer exponent?

http://stackoverflow.com/questions/6475373/optimizations-for-pow-with-const-non-integer-exponent

so you can use the integer value as an approximation of log2 . This is somewhat portably achievable by applying the convert.. by multiplying by a constant factor beforehand. x^p exp2 p log2 x exp2 p log2 x 127 127 127 127 cvtps2dq p log2 x 127 127 127.. by a constant factor beforehand. x^p exp2 p log2 x exp2 p log2 x 127 127 127 127 cvtps2dq p log2 x 127 127 127 p cvtps2dq p..
