This template is used on 3700+ pages, and changes to it will be widely noticed. Please test any changes in the template's /sandbox or /testcases subpages, or in a user subpage, and consider discussing changes at the talk page before implementing them.
This module is subject to page protection. It is a highly visible module in use by a very large number of articles, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is is protected from editing.
This module implements the {{Roman}} template. For behavioral documentation, please see the template page. For test cases, please see Template:Roman/testcases.
Module supports 0 as a Roman numeral, displays as 'N'.
Prior to 25 April 2016, used to display 69105 as LXVMMMMCV. With the addition of IX and IV being 9000 and 4000 respectively, we now display 69105 as LXIXCV.
Module handles decimal, fractional, and arithmetic expressions to a precision of 1/1728. Uses #expr: at line 118.
Find the Roman numerals for the integer part of the number.
If the number is not an integer:
Add half of the smallest unit (1/1728) to simulate rounding instead of truncation.
Ensure this new result is between 1/1728 and 1727/1728. (actually 1.1/1728 and 1727.1/1728 due to floating point rounding issues)
Hence, 0.00001 is guaranteed to have at least the smallest unit symbol (instead of being blank or 0), and 99.99999 does not display as 100 or 99 and 2 halves.
