: Er, you need to explain a little more.  Do you want Numeral system#Change of radix? --AySz88^-^ 21:46, 4 February 2006 (UTC)
thread_title:  conversion from one number to another 

message: I was always taught that there is a subset of Natural Numbers called "Counting Numbers" which consists of 1, 2, 3, 4, ect to infinity (positive integers), while a Natural Number is the same, but includes 0. Has this been changed or what? I have some references some where, most notably a college level mathbook from 2002 or something. Can someone explain this more in depth and/or why there was a change or mistake? 76.116.109.221 (talk) 03:56, 23 December 2007 (UTC)
replies: text: Most people will agree about the terms "counting number" (1, 2, 3, 4, ...) and "whole number" (0, 1, 2, 3, ...).  It is a religious issue whether the natural numbers are the same as counting numbers or the same as whole numbers.  Generally, number theorists side with the former, and set theorists side with the latter. Michael Slone (talk) 19:50, 23 December 2007 (UTC)

message: Can we have some orderings of the number systems on the page? Or a tree?
Natural numbers in Integers in Rational numbers in Constructible numbers in Algebraic numbers in Computable numbers in Real numbers in Complex numbers, for example. --Raijinili (talk) 19:22, 14 August 2008 (UTC)

message: I'm not quite sure what this adds over Number, natural numbers and other articles on specific systems and more technical articles like Set-theoretic definition of natural numbers. It seems to be largely a duplication of material which increases the editing and maintance work. Perhaphs a redirect to Number would be appropriate. --Salix alba 17:16, 23 September 2008 (UTC)
thread_title:  Exsistance of this article? 

message: Should Gaussian integer be added as a type of Number system?  This would entail adding it to the number system box at the bottom of this (and all the other number system) articles, so I feel the need to get consensus before making such a change myself.  Thanks in advance for any opinions on this question!—GraemeMcRaetalk 16:10, 5 March 2009 (UTC)
thread_title:  Gaussian integer 

message: I don't think "number system" is a coherent mathematical idea. As far as I can gather from the ones listed, an algebraic object is a number system if and only if it either has "numbers" in its name or is a real normed division algebra. What's so special about things satisfying these unnatural-looking criteria that they get an article all to themselves? An article entitled "List of people whose name contains more than four occurrences of the letter 'e'" would be equally useful.Saulglasman (talk) 17:29, 29 September 2009 (UTC)

thread_title:  What qualifies as a number system? And what is the point of this article? 

message: There is a section heading titled “Logical construction of number systems” that does not seem to be described by its subsections. Is this an old heading of a section that has been removed? If so, the sections should be renamed accordingly. Clifsportland (talk) 22:20, 6 December 2010 (UTC)
