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

Stanley <ostanley.lee@gmail.com> added the comment: Then perhaps saying that it's *never* equal is too strong, and instead we just say it's *not* equal. Not too sure how to phrase the behavior difference between `==` and `is` though, if that's something that should be noted. ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue47031> _______________________________________
