Here's my take:

die "$var non-numeric" if $var =~ /[^0-9]/; #dies if it starts with -
$var =~ s/^0*//; #this will remove any leading zeros

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
