The model field reference documentation doesn't mention that, in a
FloatField, the values must pass `math.isfinite`. This excludes
`float('inf')` (positive and negative) and `float('nan')`. I saw old
discussion about why this is the case, but only after being bitten by it
in a project. I'd like to submit a patch adding this info to the docs.

Comment (by Matt Cooper):

https://github.com/django/django/pull/16455 proposes a fix for the dev
documentation. This change could (should?) also be backported to all
supported Django versions.
