Talk:Null (computer programming)

From Wikipedia, the free encyclopedia

[edit] Unknown value

I think "unknown value" aids in understanding the three-valued logic semantics in a way that "undefined value" doesn't... "A = Null" is "unknown", rather than true or false, because Null is an unknown value which may or may not be equal to A. Kobes 19:43, 25 February 2006 (UTC)

I strongly disagree. A variable whose value has been set to "NULL" isn't intended to be "unknown" - to the contrary - it's very well known - you just set it to NULL! I don't particularly like "undefined" either...but it's better by far than "unknown". SteveBaker (talk) 00:41, 24 March 2008 (UTC)

A better synonym would be "not set" or "unset", i.e., "does not have a known value". — Loadmaster (talk) 02:30, 24 March 2008 (UTC)
