I know- Premature optimization.
But I've got code that's supposed to find out if a position is changed vs a cached position.
Current code is:
if(abs(newpos-oldpos) > 1){ }
Is it more efficient to use the following?
if(abs(newpos-oldpos) != 0){ .......

More efficient than both due to the lack of abs() , and clearer to boot.
Why not this?
if (newpos != oldpos) { ...

The ASCII() function....
To do the comparison you want you need to look at individual characters, not entire fields .
The ascii() function will only return the ascii number for the first character in an expression if you pass it a multiple character string .

Actually that Abs table will call this:
let inline abs_impl (x: ^a) : ^a = (^a: (static member Abs : ^a -> ^a) (x)) when ^a : int32 = let x : int32 = retype x in if x >= 0 then x else -x when ^a : float = let x : float = retype....

; " + "AA".TextToNumber()); Console.WriteLine("AB -> " + "AB".TextToNumber());
will produce this output:
A -> 1 B -> 2 Z -> 26 AA -> 27 AB -> 28
Update: Here's the same code but targetting.

abs() is trivial enough.
Here is one for Java (Xalan).
Here is an article about .NET xslt extensions.
It is an XSLT extension, provided by the runtime you are transforming with .
Math:abs is not built in to XSLT or XPATH.
