Convert integers to words and roman numerals

Question

Is there a library for converting integers to strings so that they (integers) are represented as words? For example:

21 => "twenty one"

I'm also interested in converting integers to strings that represent them as roman numerals:

21 => "XXI"

It's not hard for me to write conversion functions like this, but I don't want to reinvent the wheel.

Take a look at the cl format, it might return "twenty one", I used this for an euler project.

and Roman too:

~@R prints arg as a Roman numeral: IV; and ~:@R prints arg as an old Roman numeral: IIII.
