How To Determine If A String Is An Integer In Perl

Author: erics, October 28th, 2011

This solution is hyper-simplistic, and does not deal with decimals or real numbers (those with either a – or a + in front of them)…

if ($value =~ /^\d+$/) {
   ## $value is an integer
} else {
   ## $value is NOT an integer
}

if ($value =~ /^\d+$/) {

## $value is an integer

} else {

## $value is NOT an integer

}
