#19621 [NEW]: Math needs a "sign()" function

From: bill@softky.com Operating system: Mandrake linux PHP version: 4.2.0 PHP Bug Type: Feature/Change Request Bug description: Math needs a "sign()" function The wonderful math-function list is missing a very important and simple function: sign(). The is the comlpementof abs(), and together with abs() allows you to separate the magnitude and sign of a number, e.g. for graphing purposes (it's hard to graph a negative number of pixels, and displaying money as "$-99" looks dumb). It's a one-line function, so I've already written my own, but it really ought to be built-in.
