15% is a bit higher than I benchmark, but here is a version that is guaranteed to do the correct number of iterations, increments in floating point instead of performing the slow cast, and is faster than performing the comparison in floating point math (because it occupies a different execution unit). Note that it is also less accurate than the cast for most definitions of what this function might be attempting to measure. http://gist.github.com/288980 http://gist.github.com/288980
