[QUOTE="jimmifett, post: 5636769, member: 55006"] C++ is not a low level language. Sure, it is a little lower than java, a lot lower than cobol, and exceedingly lower than perl, python and ruby, but it's still a high level language, tho I'd be willing to reclassify it as mid level. Using a modulus operation, you still take more cycles to determine the modulus from a non integer division. Sure, the result is an integer, but the processer would have had to use it's normal division logic to derive it. A simple shift one step to the right bypasses all those logic gates needed to perform the complex task of division (integer or float) by doing something it's exceedingly quick at, bit fiddling.
