Algorithm Correctness

edit

I have difficulty following the algorithm's correctness for, for example, strings starting with "A". Surely in this case, we will see 0 * 26 = 0, and have no way of getting the string back - we lose information. Did I miss something? 92.232.204.226 (talk) 22:21, 7 March 2015 (UTC)Reply

I've run the calculations on the obvious case - aardvark. Results:

1. aardvark = 203723868 2. ardvark = 203723868 3. rdvark = 203723868

Obviously broken. I'm going to try to fix but I'm going on holiday soon so I'm a bit rushed haha. 92.232.204.226 (talk) 22:21, 7 March 2015 (UTC)Reply
Welp the obvious solution is just to check for a and then add 25. Not sure about how that would work in practice but gotta pack n fly! 92.232.204.226 (talk) 22:26, 7 March 2015 (UTC)Reply
Editing one last time - the above method doesn't work obviously, conflicts with z, wasn't thinking straight. The hack method seems to be to add '1' to represent b before the first iteration and then remove the first character from the string you get back. 92.232.204.226 (talk) 22:58, 7 March 2015 (UTC)Reply

Correction

edit

B/D = 2÷4 < 1. If A=1, how can B/D=A.IR...?? ...it should equal 0.M, or Z.5 70.126.175.4 02:11, 3 May 2007 (UTC)Reply

because A=0 . 66.0.13.61 (talk) 15:56, 21 May 2008 (UTC)Reply

triplicate

edit

On the 20th of may some anonymous editor was kind enough to remove some duplications in the text. It appears these corrections were immediately undone by User:Maxim. Does he like triplicate text? 66.0.13.61 (talk) 15:56, 21 May 2008 (UTC)Reply

Move?

edit

Should this be moved to Base 26, or is this faux Latin actually an English word? kwami 04:58, 27 September 2007 (UTC)Reply

hexavigesimal is listed (along with a great many others) at http://www.answers.com/topic/numeral-system?cat=technology . I first encountered the term in a VOD software interface specification. 66.0.13.61 (talk) 15:56, 21 May 2008 (UTC)Reply
Reviving this thread, yes; this Hexavigesimal should be moved to Base 26.GuyHimGuy (talk) 04:09, 16 June 2014 (UTC)Reply
Some would object to "hexavigesimal" as a mixed Greek-Latin form, but I'm not sure "Base 26" is superior... AnonMoos (talk) 08:02, 18 June 2014 (UTC)Reply

Notability

edit

I suggest the notability issues raised by sligocki are discussed here: Category talk:Positional numeral systems#Notability.--Noe (talk) 17:08, 23 October 2009 (UTC)Reply

Very, very happy. :D

edit

When I saw that you had included a c# conversion algorithm, it made my day. :D

the java code example does not generate the same column names as are used in excel

edit

in excel AAA is 676+26. The java code on the page skips columns YA-YZ? The maximum number of excel columns is 16384, which should be represented as XFD — Preceding unsigned comment added by 62.254.222.177 (talk) 13:55, 16 March 2012 (UTC)Reply

I removed the redundant and wrong parts of the section and replaced the algorithm.
