I have a string that is eight numbers and I would like to split it into two. I know that I could do it with substring but split seemed like a more logical choice. One way I did it was this:

my $thing = '12340019';
$thing = s/(\d{4})(\d{4})/$1 $2/;
my @splat = split(/ /, $thing);

But that doesn't really seem like the best way to do it. I figured that I should be able to get the effect by using split by itself and asking it to split on 4 numbers, but I couldn't get it to work. Also how would I go about changing '0019' into 19. Is sprintf the only (or best) way to accomplish that.

Thanks
