Looks like Number::Format would be an easy way to go. I haven't used it myself, but by my reading of the documentation, it would be as simple as: 

use Number::Format ':subs';

for (qw($100000000.00 $100.00 $1000.00)) {
    s/^\$//;
    $_ = '$' . format_number( $_, 2, 2 );
    print;
}

It's even easier if there weren't the dollar sign at the front.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
