As i said before the AMD-3dn-ins-set contains some new MMX commands
which are single-float-based (24Bits-range [-10e38..+10e38],
two floating-ops of the same type can be executed at a time.
I don't know if the coding-algorithm/fft-stuff will loose exactness
if the used doubles are converted to singles.
