I think you're mistaking my suggestion. I meant to recommend that
there should be a way to control the behavior (e.g. whether to
silently return Nan/Inf or raise an exception) of floating point
operations, using the capabilities of the hardware as exposed through
C, using Python's existing float type. I did not for a second consider
reimplementing IEEE 754 from scratch. Therein lies insanity.
That's also why I recommended you look at the fpectl module.
