A Roman numeral converter turns an ordinary number from 1 to 3,999 into Roman numerals like MCMLXXXIV, or reads a Roman numeral back into a number. Romans built values from the seven symbols I, V, X, L, C, D and M — worth 1, 5, 10, 50, 100, 500 and 1,000.

The system is mostly additive, writing larger symbols before smaller ones and adding them up, but it uses a subtractive shortcut for the 4s and 9s: IV is 4, IX is 9, XL is 40 and CM is 900. This converter also validates the input, rejecting malformed numerals such as IIII or VX.

Worked example: 2024 breaks into 1000 + 1000 + 10 + 10 + 4, which is MM + XX + IV = MMXXIV. Reading it back, MMXXIV adds 1000 + 1000 + 10 + 10 + (5 − 1) = 2024. Because the symbols only reach M, the largest value the standard system can write is 3,999, or MMMCMXCIX.
