Roman Digits are used to express Roman Numerals. Commonly known are the digits I, V, X, L, C, D and M. But more digits do exists, although they are not used in these days where sometimes Roman Numerals are used as (for example) index page numbers. Following digits exist.
| Digit | Value | |
|---|---|---|
| I | 1 | |
| V | 5 | |
| X | 10 | |
| L | 50 | |
| S | 90 | |
| C | 100 | |
| Y | 150 | |
| G | 400 | |
| D | Q | 500 |
| M | 1000 | |
| Z | 2000 | |
If a horizontal line is found above one or more digits, the found value must be multiplied by 1000. And to express even larger numbers, one can embed the digits in a rectangle, with the bottom line missing, meaning that the value has to be multiplied by 100000.
Example:
=165.178.316
