Wise Ones--

I've been pondering something, simple enough it would seem. In a project that I'm currently working on, I'm having to pull "dollar" values from a database that are formatted as floating point decimal numbers, and displaying them in currency format, replete with trailing zeros if there are none present. I've written a rather clunky block of code that gets the job done, but I know that there has to be a way to do this with a regular expression:

5.5 becomes $5.50
9 becomes $9.00
19.95 becomes $19.95 (unchanged, essentially)

All but the most elementary regular expressions are still my Achilles' Heel. My goal is to become a regular expression guru, but for now, the regex solution escapes me.

I humbly submit this, and eagerly await the masterful instruction.

Many thanks,
higle
