Since you're talking about mathematics, why is not y equal to -9?

because -3^2 = 9

the spaces are only visual...  that would be my guess

Why is there a discrepancy between y and z in that case? Thinking like you y should be equal to 9

"z" should also be 9

It has nothing to do with Execute() and I don't understand why it is used here. The same happens with these:

local $y = - $x^2
Local $z = 0-$x^2
local $s = -$x^2

ConsoleWrite("y = " & $y & @crlf )
ConsoleWrite("z = " & $z & @crlf )
ConsoleWrite("s = " & $s & @crlf )

y and s are exactly the same.  z is 0 minus that value

local $y = execute("-$x^2")
Local $z = Execute("0-$x^2")
local $s = Execute("-$x^2")

I do not understand.
* text "- $ x ^ 2" means (-3) ^ 2
* text "0- $ x ^ 2" means 0- (3) ^ 2
In my opinion, this is not a clear consequence.

Your posted execute statements are these formulas:

-3^2 = 9

0-3^2 = 0-9 = -9

That's how Autoit3 works as defined in the helpfile.

I am sad that it is considered normal. I can not accept it as a mathematician

If you're a mathematician, I'm the King of England. The code you posted is 3rd grade math, and you failed to be able to understand it.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
