This template converts [[Arabic numeral]]s (that is, 1, 2, 3, etc.) into [[Roman numeral]]s (I, II, III etc.). It currently works for any whole number between 1 and 4999999.

== Usage ==
{{pre|<nowiki>{{Roman|</nowiki>''number''<nowiki>|</nowiki>''message''<nowiki>}}</nowiki>}}

Replace <code>''number''</code> with the number you would like to be converted to Roman numerals. For numbers higher than 4999999 the template outputs "N/A". This can be changed by replacing <code>''message''</code> with your preferred text.

An overline, representing multiplication by 1000, is used to extend the upper range of the function.

See [[Roman numerals]] for further information.

=== Fraction support ===
The template can accept parsing decimals, fractions, and arithmetic expressions. This is not enabled by default. To enable this, supply {{para|fraction|yes}}, i.e. <code><nowiki>{{Roman|105.5|fraction=yes}}</nowiki></code> or <code><nowiki>{{Roman|105.5|too big|fraction=yes}}</nowiki></code>.

Roman numeral output for fractional values uses these symbols:
*S = ½
*''':''' = 1/6
*• = 1/12
*Є = 1/24
*ƧƧ = 1/36
*Ɔ = 1/48
*Ƨ = 1/72
*<s>Ƨ</s> = 1/144
*℈ = 1/288
*» = 1/1728
*N = 0

== Examples ==
{|class="wikitable" style="text-align:center"

|-

|}

If the number provided is negative, the template will output an error message. If the first parameter provided cannot be interpreted as a number, the template will also output an error message. If no arguments are given, the template produces no output.

'''Examples:'''
*<code><nowiki>{{Roman}}</nowiki></code>: {{Roman}}
*<code><nowiki>{{Roman|}}</nowiki></code>: {{Roman|}}
