I like to use the method listed in the perldocs. Try this:
perldoc -q "output my numbers with commas"
It lists a really cool solution, although I'm sure there are plenty of others :)
It credits Benjamin Goldberg with this:
s/(^[-+]?\d+?(?=(?>(?:\d{3})+)(?!\d))|\G\d{3}(?=\d))/$1,/g;
Hope this will work for you,
Jared
