You're quite right, though there is already plenty of platform  
dependent code in Python for just that purpose (see fpectlmodule.c,  
for instance).

Anyway, all I originally wanted was to point out that using division  
was one possible way to tell the difference that didn't involve  
relying on the representation being IEEE compliant.  It's true that  
there are problems with FP exceptions.

Kind regards,

Alastair.
