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



Replace number 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 message 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 |fraction=yes, i.e. {{Roman|105.5|fraction=yes}} or {{Roman|105.5|too big|fraction=yes}}.

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
  • ƻ = 1/144
  • ℈ = 1/288
  • » = 1/1728
  • N = 0
