Standard Roman numerals cover 1 to 3999. The number 4000 and above cannot be represented in classical notation without special overline symbols, so this converter limits input to the range 1–3999.
Roman numerals use subtractive notation when a smaller value precedes a larger one. For example, IV means 5 minus 1 = 4, and IX means 10 minus 1 = 9. This converter fully supports all standard subtractive pairs: IV, IX, XL, XC, CD, and CM.
IIII is a non-standard form sometimes seen on clock faces, but canonical Roman numeral rules require IV for 4. This converter validates against canonical form, so IIII, IIIII, VV, and similar non-standard strings are flagged as invalid.
