I was just wondering... why does it say this was posted 2008 years ago??? Unless I am terribly mistaken... we didn't have internet back then... or electricity for that matter. :)

Oh... ok sorry

I'm new to blitz and I'm sry if I am "flooding"

but you say it returns "nothing" - isn't it returning the absolute of the value passed to it? :S

This is an oversight. Most of the documentation here is generated automatically from the source code in various modules.

But Abs() is not a function. It is an operator, built into the language. So there is no source code available.

Notice that Abs() returns a value of the same type as the argument passed to it. Here are the three most common. You can tell these apart by the decimal point and the number of digits displayed.

Print

OneI:Int = 1

OneF:Float = 1
OneD:Double = 1

Print Abs(oneI)

Print Abs(oneF)
Print Abs(oneD)

I've just checked Sin() and Floor() and found that they say 'nothing' is returned as well. So my explanation is flawed. However if you browse the module source you will see that the information given here is contained in the source. So Sin(), Floor() etc. just didn't get documented properly. But the relevant information is in there somewhere.

So there is not source code available.

The source code for the Abs operator as well as many others can be found in brl.mod/blitz.mod/blitz_cclib.c :)
