  I think that Hugo was asking how good the emulator is in terms of
  numerical accuracy.

  In light of the present discussion (as to the NPX differences between
  a 387 and a 486), it is also relevant to ask which NPX instruction set
  is emulated by OS/2.  I'd expect it to be the 387, since that is the
  only significant case where one would *need* NPX emulation, but ...
