Be warned though that int isn't cleaver enough to deal with say...

$x='0';
print int($x);

still says it's a string as It is.

If you are not 100% sure then you can also do if ($x =~/^\d*$/) for an
actual integer i.e. a number in the positive whole set of numbers {
1,2,3....}  or negative whole numbers -1,-2,-3.... or 0.
