I've attached a testcase.
Running this code, I see a 36% improvement.
It also casts the floats to ints because I haven't written float_sort yet, and I don't have your fixed-point code to work with.
The benchmarks I was doing before were simply multiplying the float by 1e6 and rounding to an int. I was also only storing and sorting the actual number, not the associated data; I see that your code sorts everything. And I was measuring elapsed time rather than CPU time. I don't know how much difference any of that makes. When I simply plug the new Constants.h into my existing test I see a further slowdown; it's actually slower than std::sort.
