Template talk:Numbers

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)
