Talk:Non-standard positional numeral systems

message: I have addressed certain issues by creating the article Non-standard positional numeral systems, and making related changes to Unary numeral system, Golden ratio base, Quater-imaginary base, Positional notation, Base (mathematics), and :Category:Positional numeral systems. I suggest further discussion of these issues takes place here.--Niels Ø 14:44, 26 February 2006 (UTC)
thread_title: Article creation

message: I'm quite happy with the improvements made by others to "my" article. There is an issue bothering me, relevant to many of the articles on numeral systems: Some have a focus on the abstract mathematical idea of various numeral systems, and others focus on the cultural history of numeral systems. Many mix these two subject areas, and a clearer distinction between them would improve many of the articles. I don't really see how to do it, though. Quoting Joe Kress above, "the sexagesimal system does not contain 60 glyphs—the number varies from two glyphs in Babylonia to fifteen in the Greek form (there are ten in the modern form)." Now, that's cultural history; in the mathematical ideal sexagesimal system, there definitely are sixty somethings, that now are called numerals instead of glyphs in the article. The word glyph that I originally used was a bad choice, as it puts focus on the physical manifestation, and hence on the cultural history, and not on the mathematical idea I intended.--Niels Ø 09:18, 25 March 2006 (UTC)
thread_title: Cultural history vs mathematical idea

message: As the originator of this article, I must confess the title was a neologism. However,
#It seems to have caught on - not only wiki mirrors, but others too now use it.
#You can see the title of the article as descriptive of the contents, rather than as a generally accepted concept to be described.
#The little word "here" very early in the intro is meant to indicate that the title is not a generally accepted concept, but only a convenience used "here", i.e. in the present encyclopedia.
Still I wonder, have I sinned here?--Niels Ø (noe) 13:14, 13 June 2007 (UTC)

message: There's an interwiki link to :ja:広義の記数法 - I've no idea what that article is saying, but it clearly has material we don't have.--Niels Ø (noe) (talk) 17:02, 6 December 2007 (UTC)
replies: text: The comment above that I made nearly nine years ago still holds true. Anyone knowledagble in Japanese who can help?--Nø (talk) 11:53, 27 October 2016 (UTC)
replies: text: Using Google translate, it seems the Japanese article is about numeral systems in some broader sense, but not at all about what´we cover in this article. I have now removed the interwiki link or claim or whatever those are called today. The Korean one is OK, though.--Nø (talk) 11:54, 13 October 2018 (UTC)

thread_title:  Gray code? 

message: I've just removed a general citations-needed-tag from the article - I don't think it is relevant.
The article is little more than a brief summary of and pointer to uncontroversial information found in other wikipedia articles; if they lack sources, they should be flagged. (To my knowledge, the only thing that some editors feel is controversial is the inclusion of Unary as a Positional system - but I think that is dealt with in a satisfactory way in the article.)
And if anything in particular in this article lacks sources, that should be flagged.
As can be gathered from the posts above, the title of this article is a neologism, or (as I prefer to see it) a description of something that it was convenient to collect in one place as a separate wikipedia article. Perhaps that idea is challenged by the editor asking for sources for the concept "Non-standard positional numeral systems". Such sources do not exist! (Actually they do now - but only in the multitudes of wiki mirrors and in a few scientific articles that also have picked it up from us.)
Think of this article as similar to the many articles called "List of (blah blah)"!--Nø (talk) 13:30, 28 June 2010 (UTC)
replies: text: So the general citations tag is back; I still think it makes little sense. Possibly this article should be renamed to "List of non-standard positional numeral systems"; maybe detailed citations could be dispensed with then. (As I said above, of course the article on each numeral system must be sourced!). I'm not on top of official wikipedia policies on citations and list, but there are load of lists without citations that haven't been challenged. Or is this article too detailed to be considered a list? - Is that why someone feels it needs citations? Please explain! If it is specific statements in the article that bothers someone, please tag those rather than the whole article. -- There's also a new article called List of numeral systems (clearly still work in progress); perhaps it would be a good idea to merge the present article into that list.--Nø (talk) 07:46, 18 March 2011 (UTC)
thread_title:  Citations? 

message: Are there positional number systems where the least significant digits are on the left? Like decimal number written in reverse.  — Preceding unsigned comment added by 195.113.21.109 (talk) 10:55, 24 October 2012 (UTC)
replies: text: Some computers put the least significant byte first (and arguably they all put the least significant bit first within the byte, i.e. the LSB is "bit 0").  That's all that springs to my mind. —Tamfang (talk) 14:31, 24 October 2012 (UTC)

thread_title:  Endianness 

message: In Frederik Pohl's 1984 novel Starbust, one of the characters has to transmit a vast amount of information across space, and uses a process she calls "Gödelization": After encoding the information into an integer, she somehow reduces the integer to a short summation of integer powers (e.g. 11^4+31^3+43^17). This is somewhat different from Gödel numbering and I wonder if it's really something Gödel descrbed.  But it seems to be a candidate to put in this article. 
There are 4 Wikipedia articles that use the term "Gödelization" in passing :
Counter machine, Register machine, Turing's proof, and Algorithm characterizations

thread_title:  Another type of multi-base numeral system? 

message: There are no article or information about numeration systems for real (or more general sets) which do not require the use of a radix point symbol.
That's important because the radix point is an underutilized symbol, since it can appear only once, so it is wasteful from a coding efficiency perspective.  — Preceding unsigned comment added by 181.20.129.191 (talk) 02:51, 28 February 2015 (UTC)
thread_title:  Systems without radix point 

message: The category with the same name as this article includes the articles
* Asymmetric Numeral Systems
* Counting rods
* Ostrowski numeration
* Redundant binary representation
* Skew binary number system
that are not currently linked in the article. I haven't checked each to see if it makes sense to include them - but it would be woth looking into.--Nø (talk) 11:56, 3 November 2016 (UTC)
thread_title:  More systems? 

message: A subsection on "Asymmetric numeral systems" has been added by an IP user to the section "Bases that are not positive integers". But as far as I can tell, asymmetric numeral systems do not have a single well-defined base, so I think it belongs as a separate section following "Mixed bases" (or perhaps as a subsection of "Mixed bases"). But I do not understand asymmetric numeral systems well enough to be sure.--Nø (talk) 09:23, 31 January 2020 (UTC)
replies: text: It seems to me it should probably be a subsection of "Mixed bases," as a read-through of the article details a number system to encode data where each place-value may represent a different amount. However, it may be more useful to incorporate it into the prose of the mixed bases section rather than give it its own section at all. Given the subsections are so small, I've also been considering doing this with the subsections of "Bases that are not positive integers."

replies: text:  Standard numeral systems can be obtained as special cases of ANS, but in general case it works as stack - we can practically only put/push the last digit. Using some base b suggests that all digits have 1/b probability - asymmetry of ANS allows to modify this probability distribution to any chosen, like each digit having an individual basis. 188.147.49.134 (talk) 15:03, 31 January 2020 (UTC)
replies: text: Though I cannot claim I fully understand the reply from User:188.147.49.134, or the article, I think what it is asying is that, although inspired by mixed base systems, asymmetric systems are (in the most general case) something far more fancy that would not fit into the section on mixed case systems, but that would natrurally follow it.--Nø (talk) 18:38, 31 January 2020 (UTC)
