message: Unicode has two different characters for such a situation. "Approximately equal to" ≅ (tilde, bar, bar) and "Almost equal to" ≈ (tilde tilde). What's the precise difference? McKay 16:26, 12 February 2007 (UTC)
replies: text: Of course there isn't a single meaning for any of these symbols. You can use just about any symbol for an equivalence relation if defined so. The one you're talking about is usually read as congruency. I don't know if it has this other common meaning, but it would be rarer. There's also another symbol that's used for approximations, not in the article, which is an equals sign with diagonal dots, one above and one below. 70.112.49.77 20:04, 28 August 2007 (UTC)
replies: text: While taking a Calculus course in High School I recall my teacher mentioning using the " double tidles" for approximations, and he mentioned another symbol which I forgot the name of, however, it looked like a dot on top of a line (Similar to the upper "half" of a division symbol). For the life of me I can't remember its name, but I'm pretty sure it rhymmed with zero.. could anyone verify? Zulu Inuoe 20:44, 4 September 2007 (UTC)

text: Okay, so, if either can be used, why not mention both in the article? McKay (talk) 22:21, 8 July 2008 (UTC)
thread_title: Approximately vs Almost

message: "...such as the number π, which often is shortened to 3.14, or √7 as ≈ 2.65..." I think √7 is an approximation for e, not for π. That would probably be useful to note because there may be people who understand it as meaning that π is close to 2.65. It is also maybe useful to add 22/7 as approximation for π.  —Preceding unsigned comment added by Mverleg (talk • contribs) 15:08, 24 July 2009 (UTC)

message: I thought the symbol was a single tilde on top of a single dash, but I don't see it anywhere in this article, what is that symbol then? --TiagoTiago (talk) 14:28, 11 November 2009 (UTC)

message: In the third paragraph, "... many physical behavious -e.g. gravity ..", the word behavious looks like a typo intended to be behaviours.  However, it appears to have been corrected in the past and then reverted by another editor.  Is this a new technical term that is not in an dictionary or just a typo or a hoax word? Unless I hear otherwise and no one edits it in the next few days, I will amend it.  Kooky2 (talk) 22:30, 12 July 2012 (UTC)

message: The concept of approximation shows up in computer science in approximation algorithms. Perhaps this could be mentioned.  — Preceding unsigned comment added by 72.137.129.24 (talk) 01:34, 26 October 2016 (UTC)
