You can sort floats by casting them to integers and accounting for the flipped representation of negatives. Comparison-based sorting of floats is over an order of magnitude slower on x86 systems I've tried relative to an old Altivec. On the Altivec runtime of comparison-based sorting of floats is comparable to that for sorting integers.
Then, should you actually have this: BOOST_STATIC_ASSERT(sizeof(Cast_type) == sizeof(Data_type)); BOOST_STATIC_ASSERT(std::numeric_limits<Data_type>::is_iec559); BOOST_STATIC_ASSERT(std::numeric_limits<Cast_type>::is_integer); I would have expected sorting to work on whatever I throw to it -- a user might not even know what iec559 is. In other works, can you enable cast to int conditionally? And while we are at it, I am not sure that 'float_sort' is good name -- it is very generic and closes the door for different algorithm that might sort floats. - Volodya
