roman-numerals
===============
A library for manipulating well-formed Roman numerals.
Integers between 1 and 3,999 (inclusive) are supported.
Numbers beyond this range will return an ``OutOfRangeError``.
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``.
Example usage
=============
Creating a roman numeral
------------------------
.. code-block:: python
from roman_numerals import RomanNumeral
num = RomanNumeral(16)
assert str(num) == 'XVI'
num = RomanNumeral.from_string("XVI")
assert int(num) == 16
Convert a roman numeral to a string
-----------------------------------
.. code-block:: python
from roman_numerals import RomanNumeral
num = RomanNumeral(16)
assert str(num) == 'XVI'
assert num.to_uppercase() == 'XVI'
assert num.to_lowercase() == 'xvi'
assert repr(num) == 'RomanNumeral(16)'
Extract the decimal value of a roman numeral
--------------------------------------------
.. code-block:: python
from roman_numerals import RomanNumeral
num = RomanNumeral(42)
assert int(num) == 42
Invalid input
-------------
.. code-block:: python
from roman_numerals import RomanNumeral, InvalidRomanNumeralError
num = RomanNumeral.from_string("Spam!") # raises InvalidRomanNumeralError
num = RomanNumeral.from_string("CLL") # raises InvalidRomanNumeralError
num = RomanNumeral(0) # raises OutOfRangeError
num = RomanNumeral(4_000) # raises OutOfRangeError
