| $num =123;
|
| ($match) = ($num =~ m/(\d)/);
|
|
| print "$match \n"; # should print 3
|
| __END__

If you're wanting to find the last digit in a scalar, you'll want to
modify this to be:
($match) = $num =~ /(\d)$/;
or if there is always there characters you can also do this:
($match) = $num =~ /\d\d(\d)/;
