Compvter Romanvs (Roman Numeral Calculator)

OK, this is just for fun.

OK, no it isn't. I deal with a lot of books, including a lot of older, out-of-print books, and I have to struggle with converting copyright dates from Roman numerals into the sorts of numbers we generally use these days. Something that tries to make playing with Roman numerals fun is a welcome change.

If the link goes bad, it's a feature at math.com, in the Wonders of Math section.
