Display a navigation box at top of a category page for a specific Roman numeral value, and auto-categorize this category.

Usage

{{RomanCat |1= |n= |alt= }}

Usage:
{{RomanCat| 1=Roman numeral (text string)| n=its numeric value}}
or {{RomanCat|Roman numeral (text string)| n=its numeric value}}
Examples:
{{RomanCat| 1=MCXXI| n=1121}}
{{RomanCat| 1=IIII| n=4}}
{{RomanCat| 1=LXVI}} (missing n: also works, but with poorer categorization)
Advanced parameters:
{{RomanCat| 1=CↃIↃXCVX| alt=MDXCVX}} (to add a more usual equivalent which is, however still atypical)
{{RomanCat| 1=CMↃ| n=100000| comm=Agrippa dixit}} (free form text comment)

Template parameters

ParameterDescriptionDefaultStatus
1romanRoman numeral, most often using Latin letters in [IVXLCDM] and overline diacritics (as in M̿M̿M̿M̿C̿M̿X̿C̿I̿X̿C̅M̅X̅C̅I̅X̅CMXCIX which represents 4,999,999,999, the maximum numeric value representable in plain text as a typical Roman numeral with the current Unicode encoding). Lowercase letters may be used. An atypical Roman numeral may also be specified, possibly using atypical combinations (such as MMMM, or LL), or one letter in [NO] for zero (nunc in classical Latin was not really considered a numeral, there was initially no zero), or non-classical Latin letters (in [JUWY], used as uncommon ligatures or alternate forms), or archaic numeral forms (in [ƆɔᴐↃↄ∞ↀↁↂↅↆↇↈ]). If this parameter is omitted or empty, nothing will be rendered by this template.emptyoptional
nvalueThe integer value associated to the Roman numeral given in parameter {1}, using Western Arabic digits in [0-9]. This parameter is strongly recommended. Otherwise, the category may be poorly categorized.emptyoptional
altFor any atypical Roman number given in parameter {1}, specifies its more usual Roman numeral equivalent, using only letters and diacritics in [IVXLCDMI̅V̅X̅L̅C̅D̅M̅I̿V̿X̿L̿C̿D̿M̿], and containing no overlong subsequence of identical base letters (at most 3 for letters in [IXCM], or 1 for letters in [VLD]).emptyoptional
commFor any atypical Roman number given in parameter {1}, comment shown about its use or uncertain valueemptyoptional
nocat1If non-empty, disables some autocategorizations within categories not intended to contain only Roman numerals (which could be disambiguated by some added suffixes)emptyoptional
debugSet this to an non-empty value, only for debugging (when previewing a category page using the template and inspect some values). Do not use permanently.emptyoptional
