Hi Larry,

> 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.

Indeed, this is a nice use case! This is also something I encountered
a few times.

> I haven't had a use for is_representable_as_float() that I can recall.

Just thinking out loud, if this RFC ever makes it to the voting phase,
maybe we should have two separate votes, one for each function.

Best,
