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){ .......

Don't try to optimize comparison operators to equal operators; they should have the same timing, and only have the same value ... .
}
More efficient than both due to the lack of abs() , and clearer to boot.
Why not this?
if (newpos != oldpos) { ...

Specifically, Sql Server 2005/T-Sql. I have a field that is mostly a series of two characters, and they're all supposed to be upper case but there's some legacy data that predates the current DB/System, and I need to figure out which records are in violation...

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 .

Here are the results of a little test I did this evening.
Now I am no Alien racer, far from it. In fact I'm a pretty average paced guy that uses a wheel and cockpit view and I find the AI usually far to easy in this game.

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());
