[Python-Dev] Re: Should we require IEEE 754 floating-point for CPython?

- Should we require the presence of NaNs in order for CPython to build? - Should we require IEEE 754 floating-point for CPython-the-implementation? - Should we require IEEE 754 floating-point for Python-the-language? I don't have strong opinions on the first two, but for the language definition, I think the most we should say is "if an implementation does not support IEEE 754 floating-point, this must be mentioned in the documentation as an implementation limit."
