I have multiple times just recently had need of "I have a numeric string=
, should I cast it to an int or a float?", for which an is_representable=
_as_int() function (or similar) would be quite helpful, and neater than =
the messy solution I usually use.

I haven't had a use for is_representable_as_float() that I can recall.
