[issue47031] math.nan should note that NANs do not compare equal to anything

[Vedran Čačić]

I'm not satisfied with "and" formulation. For all practical purposes, math.nan is the "same" object as float('nan'), they just represent two ways of referring to it (or constructing it). To me it sounds a bit like "2 and 1+1 are the only even prime numbers." I suggest the docs only speak of math.nan here, and elsewhere to say that they can also be constructed by float('nan').
