Abs != Modulo

Hi,

The description on the following wiki page is incorrect.

Modulo is the operator that is usually symbolized by % and returns the remainder when a number A is divided by a number B.

float Abs (float A) [static]
Returns the absolute value (also known as the modulo) of A, usually written |A|. Eg: Abs(5) == Abs(-5) == 5.

Oops, yes I guess I can do that myself .

P.S: The idea of wikis needs a overhaul. At the moment, you have the equivalent of a super version of wordpad with an incremental save system. What needs to be done is to make things so information is cut up into basic units that can be imported/exported/reused/combined.

The function or my comments about wikis ?

Here's a quick reply to enlighten you :

Abs : Absolute value or value without minus sign.
Modulo : Divides a number by another number and gives you what's left. It's a great way to test if it can be properly divided by or is a factor of something.
!= : Not equal to (but I suppose you knew that)

As for wikis, well they have some drawbacks. One of them is that they have to be managed with authority which in itself could introduce bias. Also, information is mostly managed as pages of text or subpages. This means that refactoring content can prove a pain. Also, you can't really extract pure information from a wiki like you can with a database. In short, it's the modern day equivalent of a book.
