Representations[edit]

The "in computer science" section could use a few links to non-standard representations (like, BCD or 7-segments). -- Jokes Free4Me 17:29, 3 September 2007 (UTC)

Why does it say Arabic numberals?[edit]

Why does the picture on the right say Arabic numerals, when Arabic numerals came from the Hindu system? I mean when you click that link it says how it came from the Hindu system them. So why does this link say Algebraic? I mean why Algebraic? Cus that leads the person to maybe think that this came from Arabic. But it actually came from Hindus then, and then to Arabic right then? Well I think it say's something like that when you click the link itself which I think is under the picture then . 71.105.87.54 (talk) 22:40, 14 November 2009 (UTC)

Indians did not use these numerals (shapes for the digits). The system which we use digits to do arithmetic is the Hindu-Arabic numeral system, but the digits themselves are from Western Arabic sources and are called Arabic numerals. I don't know why your talking about Algebraic, that has nothing to do with this. Cheers, — sligocki (talk) 15:55, 15 November 2009 (UTC)

Alternative bases[edit]

There is a section about computer bases and balanced tertiary, so why not the main alternative base dozenal? Or the Tonal system? Both of these feature different extensions to the standard Western Arabic digits.

On a different point, also nothing is said about the larger bases like 60. In these, it is worth noting that a digit is made up of two characters, i.e. in 36:3060 = 2190, the digits are "37" and "30". 2.103.89.101 (talk) 19:09, 29 July 2011 (UTC)

Origin[edit]

I have no deeper knowlidge of the history of the ten digits. In (swedish) school we were teached that the digits were arabic. But far later a friend from Iran told me that the origin of the digits was persian, and somtimes called "arabic digits" in the west only due to the fact that europeans got them from the arabs. But even later I heard a professor (or alike) in television arguing that the ten digits originally came from India and sanskrit. Boeing720 (talk) 15:45, 31 March 2012 (UTC) what number system we use is indo-Arabic number system went from india to arab and from there to the west. This is a distorted history that the number system we use is Arabic numerals. How can there be a number system without zero. — Preceding unsigned comment added by 99.89.0.61 (talk) 03:06, 8 May 2014 (UTC)

Roman numerals under "Numerals in most popular systems"[edit]

This figure of "A" for 5000 does not come when searching generally. The wikipedia on roman numerals puts "V" with a bar aove it as a way of denoting 5000. I also have a problem with Roman numerals being listed in the table of base ten systems which have discrete figures for different numbers. The difference is that if you want to write the date 1920 in arabic figures or tamil etc... you just string those figures together (for the sake of argument let's ignore different calendars). With Roman numerals 1620 is not IVIII[zero], it is MCMXX. I am proposing that it is simply included below the table but not in it (as it already is) but with the "I" and "V" added and the "A" removed. Other numeral systems similar Roman numerals (the Chinese and Ge'ez) should be afforded the same treatment. One further note is that the "additional numerals" should be in a table. 90.195.140.219 (talk) 20:47, 2 December 2012 (UTC)

I have put the additional numerals in a table. I have left the chinese, Ge'ez and Roman in the popular systems table because it is not fitting to only have them in the "additional numerals" section. There is a disparity with having the full roman system in the additional table, while only larger abbreviation of the chinese system are there. I cannot currently think of a way around this, besides listing all numerals in one table. Of course, most numeral systems don't have a symbol for 10^12 but are happy to keep adding zeros or to use SI, so it would mean many blank boxes. Also, there needs to be some table editing to make the columns of uniform width, but i don't know how to do that. 90.195.140.219 (talk) 21:15, 2 December 2012 (UTC)
