Regexp::Common is a godsend for this sort of thing, absolutely! The problem is still complicated, though. OP hasn't said what this will be used for, but number formats are vry locale specific, particularly currency formats. '$###,###.##' isn't the only way to represent a dollar amount, and if this is going to be used for any sort of external audience, you'll want to be prepred for a variety of input. For the amount "one thousand U.S. Dollars," the following are all popular representations: $1,000.00 $1000.00 $1000 USD\s?1000 USD\s?1000.00 1000 USD 1000.00 USD USD\s?1000,00 USD\s?1.000,00 USD\s?1 000,00 $1.000,00 $1 000,00 1.000,00 1 000,00 Which of the options you can expect to get as input will depend on the context in which the question is asked, and where your users are physically. This is a particular nuissance for web designers.
