Roman Numerals and Zero
Classical Roman numerals represent positive integers beginning at one. Among the seven standard letters I, V, X, L, C, D, and M there is no zero. Later discussions of nulla/N are scholarly footnotes, not an eighth converter digit.

No zero in the seven-letter set
This site’s tools accept 1–3999. Attempts to represent zero after subtraction (for example V − V) are explained rather than rendered as a Roman glyph. See also Roman numeral zero and the calculator.
Nulla / N notes
Some later writers discuss nulla (“none”) or N. Treat those as historical/academic notes. They are not accepted as inputs by the converter.
