I have a series of double variables, that can be anything from 0.00, to 000.00. What I want is to add leading zeros so that they all line up:

From:
$ 5.66
$ 12.12
$ 122.42

to something like:
$ 005.66
$ 012.12
$ 122.42

or better yet, a way to do:
Code:
$   5.66
$  12.12
$ 122.42

(forums messed up the spacing, sorry)
any ideas?
