Try Perl. Regex below picked from Perl Cookbook, section 2.17.

Code:
[user@ubuntu dir]# echo 12345678911234567 | perl -lne 'chomp; $x=reverse; $x=~s/(\d\d\d)(?=\d)(?!\d*\.)/$1,/g; print (scalar reverse $x)'
12,345,678,911,234,567
[user@ubuntu dir]#

This takes care of putting commas in float numbers like 123456.789 etc.
