[issue40633] json.dumps() should encode float number NaN to null

Eric V. Smith added the comment: I think that's reasonable, although I could see someone objecting ("just use simplejson instead"). I suggest discussing this on the python-ideas mailing list and see what people think over there. It might help to create a PR first, if it's not a lot of work.

[issue40633] json.dumps() should encode float number NaN to null

Haoyu SUN added the comment: Thank you for the timely reply, Eric. How about we add an optional argument (like the argument "ignore_nan" defaults to False as the package simplejson does) to functions like json.dumps(). So that user can choose whether he needs NaN encoded as NaN or null,

[issue40633] json.dumps() should encode float number NaN to null

Eric V. Smith added the comment: Since this is documented behavior (https://docs.python.org/3.8/library/json.html#infinite-and-nan-number-values), we can't change it by default without breaking code. What JavaScript JSON encoders and decoders specifically have a problem with this behavior?
