[VPM] detecting non-integers

[Carl B. Constantine]

I have a web CGI that I'm modifying. I want to make it so that you can
only input an integer number. So if anyone tries to type 10.44, it is
detected by my CGI and refused.

Since perl doesn't have types as such, what is the best way to detect
this, just a regex like: =~/\d+(\.)*/ or is there an easier way?
