CPUs without HW FPU are not necessarily low performance for integer
calculations. I don't know anything about wavpack, but from the
wikipedia page it seems like it doesn't use much FPU:
No floating-point arithmetic is used in WavPack's data path because,
according to the author, integer operations are less susceptible to
subtle chip-to-chip variations that could corrupt the lossless nature of
the compression (the Pentium floating point bug being an example). It is
possible that a lossless compressor that used floating-point math could
generate different output when running on that faulty Pentium. Even
disregarding actual bugs, floating-point math is complicated enough that
there could be subtle differences between "correct" implementations that
could cause trouble for this type of application.
So I would just drop this sentence.
