FloatFormatType is too wide, as it includes any Callable.
Can you change FloatFormatType to use Callable[[float], str] instead of Callable in _typing.pyi, and then you don't need the Callable declaration here or elsewhere?

I was going to suggest that indeed since we should collapse those two parts.
This is addressed.

float_formatin.to_stringcan bestr#730assert_type()to assert the type of any return valueShould fix the issue, yet passing an
strtofloat_formatwill depend on the underlying type, for example for a float it will work totally fine but for numpy Float64 it won't work.So the typehints are correct to the extent that it also works at runtime.
Docs are not fixed yet, seems like the issue on the pandas repo is stale pandas-dev/pandas#53675
