I quote:
I have decided to not use any floating-point arithmetic in WavPack's data path because I believe that integer operations are less susceptible to subtle chip to chip variations that could corrupt the lossless nature of the compression, the recent Pentium floating point bug being a blatant example of this.

Is this obsoleted, in the sense that Bryant has found that one can now trust floating-point arithmetic, or does it mean that even floating-point .WV files are created using fixed-point arithmetic, without any use of the processor's floating-point internals?

(Edited for clarification.)

This Wikipedia article describes the 1994 Pentium floating point divide bug. I have not heard of any such bug since then.
