[edit] Move?

Given that the current AFD discussion appears to be headed toward a "keep" result, should this page be moved somewhere after it is over? Maybe Negative zero? NatusRoma 20:11, 17 October 2005 (UTC)

How about −0? (That's minus zero rather than "hyphen zero".) —BenFrantzDale 05:04, 20 December 2005 (UTC)

I second −0 (minus zero) like BenFrantzDale suggested. —Liyster 01:25, 12 January 2006 (UTC)

I've moved it to −0 (number), for consistency with −1 (number) and −40 (number). sjorford (talk) 20:59, 15 January 2006 (UTC)

[edit] Properties and handling

Shouldn't we specify that x/0 is undefined? It's lim(x/n,n,0) = infinity, not x/0 = infinity.

But in IEEE 754, it isn't undefined! Melchoir 01:27, 25 October 2006 (UTC)

[edit] Programming languages

The article is a bit unusually inaccurate on this issue. The C family is mentioned and so is Java, but the function that "should" be used instead seems to be a C/C++ function, apparently without a Java equivalent (as none is mentioned). I don't recall Java having the problem, though that doesn't have to mean it doesn't exist. It seems odd to advise programmers in general to use a specific function that seems to be C-specific.

If the standard is language independent, refering to the name of the function doesn't make much sense unless most libraries have it (the equivalent functions for other languages should be named too), otherwise the programmer would be advised to implement it, rather than use it (because it wouldn't be a function, but merely a language independent description of a function). — Ashmodai ^{(talk · contribs)} 23:06, 26 October 2006 (UTC)
