Template:Roman Numeral

Template documentation[view] [edit] [history] [purge]

This template uses Lua:

Module:Roman Numeral

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 though numbers may be increasingly hard to read the larger they get.

UsageEdit

{{Roman Numeral|number}}

Replace number with the number you would like to be converted to Roman numerals.

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

See Roman numerals for further information.

Fraction supportEdit

The template can accept parsing decimals, fractions, and arithmetic expressions. Though this may have varying results and is not incredibly accurate. It can currently do decimals in increments of 1/24ths.

Roman numeral output for fractional values uses these symbols:

S = ½
: = 1/6
• = 1/12
Σ = 1/24

ExamplesEdit

Arabic numerals	Template call	Roman numerals
0	{{Roman Numeral\|0\|explanation=yes}}	N 0 is represented by N
-1	{{Roman Numeral\|-1}}	-I
1	{{Roman Numeral\|1}}	I
2	{{Roman Numeral\|2}}	II
49	{{Roman Numeral\|49}}	XLIX
50	{{Roman Numeral\|50}}	L
51	{{Roman Numeral\|51}}	LI
1024	{{Roman Numeral\|1024}}	MXXIV
4999	{{Roman Numeral\|4999}}	MↁCMXCIX
5000	{{Roman Numeral\|5000}}	ↁ
5001	{{Roman Numeral\|5001}}	ↁI
69105	{{Roman Numeral\|69105}}	ↇↂMↂCV

As is apparent, if the number provided is negative the number will have negative polarity when outputted (represented by the minus sign prepended to the number). If the first parameter provided cannot be interpreted as a number, the template will output an error message. If no arguments are given, the template produces no output. If the first argument is a number but is below 1/24th then no output will be produced. Any number above 1/24th will produce an approximate result.

Examples:

{{Roman Numeral}}:
{{Roman Numeral|}}:
{{Roman Numeral|0.0005}}:
