[edit] -0

• Delete Hoax Nonsense StephenJMuir 20:09, 14 October 2005 (UTC)
  • Keep This page has not been expanded: it has been completely replaced. It was originally an article on -0 in the field of mathematics, in which -0 is and always will be equal to +0. It is now an article on -0 in the field of computing, which is perfectly valid. StephenJMuir 10:07, 16 October 2005 (UTC)
• Delete per nom. Keep per rewrite and link provided by User:Pilatus. Good work all on sourcing this and writing a useable article on the topic.--Isotope23 20:38, 14 October 2005 (UTC)
• Delete. What? the wub "?!" 22:58, 14 October 2005 (UTC) Keep per Pilatus. the wub "?!" 09:28, 16 October 2005 (UTC)
• Delete. NatusRoma 05:28, 15 October 2005 (UTC) Keep per User:Pilatus. NatusRoma 03:08, 16 October 2005 (UTC)
• Delete this wasn't speedy deleted because??? Masterhatch 10:26, 15 October 2005 (UTC) With the added info and sources, I change my vote to Keep. Masterhatch 03:43, 16 October 2005 (UTC)
• Keep. THIS IS NOT A HOAX as a this link will tell! Negative zeroes do occur in one's complement arithmetic. Pilatus 00:49, 16 October 2005 (UTC)

• Delete. There is no negative zero. There may be a position in computer memory that is used to indicate the sign in non-zero numbers. A bitstring in a computer may be the same as zero except for that position. That does not make it negative zero. A more sensible use for that bitstring would actually be undefined value. −Woodstone 12:48, 16 October 2005 (UTC)
• Keep. The article needs more work, and it should be noted that the -0 is usually a PITA, and one reason why 2's complement is preferred. -- Egil 13:01, 16 October 2005 (UTC)
  • Actually, 2's complement has its problems too. For example, an 8 bit 2's complement number has values in the range -128 thru +127. If you evaluate -(-128) you get -128 rather than +128! StephenJMuir 14:39, 16 October 2005 (UTC)
    • Actually what you get is overflow; up to you to interpret the validity and value of the result. −Woodstone 15:54, 16 October 2005 (UTC)
• Keep. The concept of negative zero indeed exists in many floating point representations. -- Jitse Niesen (talk) 15:02, 16 October 2005 (UTC)
• Keep. John Walker even dedicated a whole page to this subject. [1] squell 05:11, 17 October 2005 (UTC)
• Keep. The current page is completely different from the one nominated, and is now a valuable contribution to Wikipedia.-gadfium 20:06, 17 October 2005 (UTC)
• Keep as above, possibly expand beyond computing. The original article didn't make too much sense, but it contained an apparent allusion to the temperature of -0 in statistical mechanics, which would be an interesting thing to discuss in the article. --Trovatore 20:33, 17 October 2005 (UTC)
• Keep PrimeFan 20:42, 17 October 2005 (UTC)
• Keep. Itz 4 realz yo. It belongs in Category:Computer arithmetic, where there are many other weird applications, approximations, and abstractions of mathematical concepts. It is even referenced in W3C standards [2]. Current article text is looking OK. — mjb 01:39, 19 October 2005 (UTC)
