How it works: Roman numerals converter

Roman numerals use seven letters: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500 and M = 1,000. Read left to right and add, except that a smaller numeral before a larger one is subtracted: IV = 4, IX = 9, XL = 40, CM = 900.

No letter repeats more than three times in a row, so the largest number is 3,999 (MMMCMXCIX).
