This is an improved version of the existing Template:Roman.
Written on 13 Mar 2009. Ideas implemented into practice on 25 Apr 2016.
This template converts numbers into Roman numerals, using the following symbols:
| Symbol | Value |
|---|---|
| M | 1000 |
| D | 500 |
| C | 100 |
| L | 50 |
| X | 10 |
| V | 5 |
| I | 1 |
| 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 |
An overline, representing multiplication by 1000, is used to extend the upper range of the function.
See Roman numerals for further information.
Usage
[edit]{{Roman | number | error_message }}
Where:
- 'number' is a numeric value subject to the following limitations:
- The largest number that this template will correctly process is 4,999,999 1727/1728 (which will be resolved as MMMMCMXCIXCMXCIXS:•:ЄƧƧƻ℈»»»»»). The template will return an error message if any argument is used that is larger than this.
- A negative argument will result in the template returning an error message.
- Arguments are rounded to the nearest 1728th, since this is the highest level of precision that this template includes.
- 'error_message' is the text to display if the template cannot handle 'number' (i.e. 'number' is either too large or is negative). If left blank, the function will use descriptive error messages.
A blank argument will be treated as a zero value. A text argument will cause an 'Unrecognised word' error in the mathematical expression parser.
