How this system works
Positional bases are not physical units, but they are rival systems for writing the same integer. Binary, octal, and hex are the computing trio; Roman numerals are additive and only cover 1–3,999 here. Input is treated as a whole number.
Base unit: integer. Decimal is Other; Hexadecimal is Other.
