NaNs and infs are IEEE-754 concepts. Python does run on non-IEEE-754 platforms, and I don't think that python-dev will want to entirely exclude them. You will have to do *something* about those platforms. Possibly, they just won't support NaNs and infs at all, but you'd have to make sure that the bit pattern that is a NaN on IEEE-754 systems won't be misinterpreted as a NaN on the non-IEEE-754 systems.
Sounds like some clever #ifdefs is needed here. How does isnan() dealing with this?
It doesn't. numpy does require IEEE-754. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
