--[[This module converts Arabic numerals into Roman numerals. It currently works for any non-negative integer below 5 billions (up to 4 999 999 999).
The Roman numerals, in particular, are directly derived from the Etruscan number symbols: š , š” , š¢ , š£ , and š for 1, 5, 10, 50, and 100 (they had more symbols for larger numbers, but it is unknown which symbol represents which number).

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 ...
The higher-order function that represents natural number n is a function that maps any function to its n-fold composition. In simpler terms, the "value" of the numeral is equivalent to the number of times the function encapsulates its argument.
A special series of numeral adjectives was used for counting these, namely Å«nÄ«, bÄ«nÄ«, trÄ«nÄ«, quadrÄ«nÄ«, quÄ«nÄ«, sÄnÄ«, and so on. Thus Roman authors would write: Å«nae litterae 'one letter', trÄ«nae litterae 'three letters', quÄ«na castra 'five camps', etc.

I.E. make it clear that the negative numbers are out, not just this one or some of them. All the best: Rich Farmbrough, 20:07, 23 April 2016 (UTC).
Grouped by their numerical property as used in a text, Unicode has four values for Numeric Type. First there is the "not a number" type. Then there are decimal-radix numbers, commonly used in Western style decimals (plain 0–9), there are numbers that are not part of a decimal system such as Roman numbers, and decimal numbers in typographic context, such as encircled numbers.
