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, Alexandre Daubois
