{{Roman|number|message}}

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.

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 = 1⁄2
• : = 1⁄6
• • = 1⁄12
• Є = 1⁄24
• ƧƧ = 1⁄36
• Ɔ = 1⁄48
• Ƨ = 1⁄72
• Ƨ = 1⁄144
• ℈ = 1⁄288
• » = 1⁄1728
• N = 0

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.
