Greetings fellow monks,

A friend of mine was bug checking a script I wrote and wondered about comparing strings to numbers, and via that conversation, I wondered about parsing strings for numbers. I've never really worried about it until now. What I've come up with seems both crude and prone to problems. Is there a better/smarter way to go about this?

#!/usr/bin/perl
use warnings;
use strict;

my $string = '123.45abc';
print parseInt($string), "\n";
exit;

sub parseInt {
  my $val = shift;
  $val++;
  $val--;
  return $val;
}

Looking at JavaScript, you can functions like parseInt or parseFloat fairly safely. Any ideas for Perl?
