# Roman numeral dating

I must admit that I have not yet checked the links you give, but if Wikipedia has to be consistent as a whole, this article must agree with Decimal (and with Decimal representation).In those articles, and for what I know in the current use of the word (when talking about numeration systems), a decimal numeration system is before anything else a positional system, that is, one in which each digits gets a meaning depending on where it is in the representation of a number.), or is it a coding error by whoever wrote the table? Therefore 5 cannot proceed any number larger than 50.12. Rob (talk) , 24 February 2009 (UTC) I only learned Roman Numerals intuitively. They are used only to create 4's and 9's.--Sport Wagon (talk) , 24 February 2009 (UTC) Thinking about the confusion made me realize that I keep Roman Numerals straight by thinking of them as decimal digits (with never any zeroes, but all digits are actually "scaled" by the appropriate power of ten).77.102.101.220 (talk) , 8 November 2009 (UTC) Hi there, I came on here to determine the exact definition of roman numerals, and the article contradicts itself as far as I can see. The page says "10^n may not precede any symbol larger than 10^(n 1)". But it seems that only integer powers of ten can be used to "decrement" a decimal digit. But when I over-think about that, it seems it should be wrong. --Sport Wagon (talk) , 24 February 2009 (UTC) The spoken language was decimal.A Roman Numeral can be visualized as its decimal digits, and omitted zero placeholders (which are unnecessary because the magnitude is explicitly indicated by the choice of symbols).It's not like the symbols represent dozens and gross, or other truly non-decimal quantities.So in "13" the digit "3" denotes three units, while in "31" it denotes three "tens", and so on.So merely the fact that some of the symbols used in Roman numerals denote powers of ten is not sufficient to qualify it as "decimal".

You keep doing that until you get to the top of the table. The table defines the combinations which can occur in valid (modern) Roman Numerals; it is more restrictive than more general rules would imply.--Sport Wagon (talk) , 25 February 2009 (UTC) A revision comment states that the Roman Numeral system is definitely not decimal.If you would like to participate, please visit the project page, where you can join the discussion and see a list of open tasks.This article falls within the scope of Wiki Project Writing systems, a Wiki Project interested in improving the encyclopaedic coverage and content of articles relating to writing systems on Wikipedia., a group of contributors who write Wikipedia's Classics articles.If you would like to join the Wiki Project or learn how to contribute, please see our project page.
