Unless the bitpaths in the chip always ran (in parallel) at double
precision levels even with float values, and any algorithms for 
double were more heavily optimized because thay were always used
and were the only oines that really mattered.

Besides, float runs in parallel chip units and thus only pipelined
operations that interact with shorter integer pipelines will ever be 
seen to slow the main intergral code processing.
