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

Stanley <ostanley.lee@gmail.com> added the comment: Vedran's got a good point, as existing documentation for math.nan already says "... Equivalent to the output of float('nan')." so it does seem a bit redundant to say both, though I wonder if we should still be explicit since

...

import math math.nan is math.nan True float('nan') is float('nan') False

so they don't have the exact same behavior. Serhiy also has a good point, so maybe instead say that Math.nan/float('nan') is *generally* not equal to any other value? ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue47031> _______________________________________
