Not sure where this is notion comes from.
Terry Reedy's post provides a datapoint to the contrary.
Besides, there is no problem along these lines that
can't be cured by a better method name:
f.integer_portion()
Also, if you go the method route, then the API can easily
be expanded to cover all the normal rounding methods:
f.round_to_even()
f.round_half_up()
...
These are all specific and explicit.
Also, we can take advantage of the ABC mixin capabilities
to automatically provide all of these given one or two of
them as primitives.
