The OP did not specify the domain of possible inputs nor the desired
output for all possible inputs. Without that, function design is
guessing. The appropriate response to the original post would have been
a request for clarification.
If the domain is strings with and int followed by '.0', then chopping
off two chars is sufficient. This was sort of implied by the original
post, since it was the only example, and assumed by the respondant.
If the domain is int literals followed by '.' and some number of zeroes,
then split works. So does int(float(s)). Split also works for non-digits
following '.' whereas int(float(s)) does not.
If the domain is all float literals, then ??????.
