textproc/py-roman-numerals 4.1.0p0 OpenBSD

A library for manipulating well-formed Roman numerals, supporting integers between 1 and 3,999 (inclusive).

The classical system of roman numerals requires that the same character may not appear more than thrice consecutively, meaning that 'MMMCMXCIX' (3,999) is the largest well-formed Roman numeral. The smallest is 'I' (1), as there is no symbol for zero in Roman numerals.

Both upper- and lower-case formatting of roman numerals are supported, and likewise for parsing strings, although the entire string must be of the same case. Numerals that do not adhere to the classical form are rejected with an InvalidRomanNumeralError.
