Template talk:Numbers

PLEASE NOTE
It seems not clear to some visitors (in view of the latest 3 edits, e.g. ) that the "Templates" displayed below are by now largely outdated versions which have (luckily) almost nothing more in common with the current version, so it's of no use to make corrections to them here. &mdash; MFH: Talk 20:49, 21 Jun 2005 (UTC)

PS:maybe those appearing there could be "cut down" to the parts that are discussed here, which would at the same time avoid confusion and save space. &mdash; MFH: Talk

PPS: IF s.o. wants to change the template, please also replace \ne\Q by \notin\Q at "e (constant)".

duplicates
The heading "complex extensions" occurs twice in this template which looks like an error. Being Danish, I shall avoid any other action than this comment :-). Kind regards --83.88.250.55 10:55, 26 Apr 2005 (UTC)

In addition, the line "Reals" contains a { that should be removed. --83.88.250.55 16:27, 26 Apr 2005 (UTC)

No, in fact the lines "Real numbers" and "Reals" both refer to the same article, so the latter should be removed entirely. --83.88.250.55 16:40, 26 Apr 2005 (UTC)

I would encourage you to login and edit it. I personally struggle with how best to represent or organize complex and trancendental numbers, and am unsure how much depth it should have. In any case, Id prefer that someone more knowledgeable edit it, and that's the main why it was posted on the numbers article. I will take a look now at making some changes, but would encourage you to Be Bold in editing. -SV|t|add 20:43, 26 Apr 2005 (UTC)

Suggestion for template:Numbers
Please find below my suggestion for rearranging the template. The changes I've made are the following:
 * for naturals, I specified 1/2, 1/3,2/3,1/4 etc. according to "normal" notation
 * I've tried to arrange the list of elementary better according to quantity. I´m not sure about the right positioning of computable and split-complex numbers
 * I removed i and Tr from the real numbers - I don't think they belong there.
 * I removed a dual entry/link for real numbers (reals)
 * I added the transfinite numbers to the list
 * pi, i, and e were moved to the last section. They are the basic symbols of geometry, complex numbers, and logarithms, respectively (and elements of the famous Euler equation)
 * I tried to find a proper heading for the last section. Improvements may be found.
 * and, finally, a small amount of editing

Please have the list inspected by a mathematician - I'm just an informed amateur :-).

Kind regards, Sir48 (Denmark)

PS! I entered the existing template to the left for easy comparison.


 * Thanks! I was moving it to the right, just as you were moving it left. Thanks again, Ive incorporated your suggestions into the list above, and am working on making small images in place of the larger math formula renderings. Size is a factor. :) -SV|t 00:55, 28 Apr 2005 (UTC)
 * Understandable :) Came to think about imaginary numbers again. I added them to the list. Some might argue that "imaginary numbers" don´t exist, the precise entity being: The imaginary part of a complex number. Regards Sir48 (Denmark)


 * I couldn't resist moving imaginary numbers to their proper place. Also, I changed the exemplification of rationals to make the template smaller. Regards Sir48 (Denmark)

T for transcendentals??
I object vigurously to the BBB 'T' for transcendentals, at least(!) 99% of all mathematicians would recognize this instantly as the torus and never think of transcendentals (btw, this symbol isn't even mentioned on the corresponding page). &mdash; MFH: Talk 22:10, 12 May 2005 (UTC)
 * Agreed. Let's see if anyone complains when I remove it. Algebraist 15:49, 22 November 2007 (UTC)

Template too big
The current template crowds out the article for the first screen and a half on my usual browser screen size: this is too big. The usual use of these templates is to indicate an article series that one thinks the reader might read in chronological order. I propose that the current template be used to seed a wikiportal on number (there is Wikiportal/Mathematics already), and a much more condensed template be written from scratch. --- Charles Stewart 5 July 2005 22:14 (UTC)

imaginary
shouldn't the imaginary unit be rendered $$i$$? — Omegatron 20:14, 19 October 2005 (UTC)

Move template:Numbers into category:Numbers ?
Would it be a good idea to move all links that are contained in the template:Numbers into additional text on category:Numbers? This would allow to add some more text around the individual links, and the template wouldn't show-up at so many other places. There are some other concerns about this template, I have written some in Category_talk:Numbers. Thanks, Jens Koeplinger 16:58, 20 July 2006 (UTC)
 * Sorry about my confusion, I'm still getting familiar with categories, templates, and articles. I meant to update the article Number. There appears to be some consensus, but I want to double check. Thanks, Jens Koeplinger 17:03, 20 July 2006 (UTC)

Reorder
While I agree that the template is too big, I did some reordering, because some of the types were obviously not under the right caption. The template should really be compactified somehow. ... But how? Anyway, for now the types are at least under some better category, hopefully. Thanks, Jens Koeplinger 01:38, 16 January 2007 (UTC)
