Bug in Execute function

[edzioedzio55]

Local $x = 3

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

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

 

output:

y = 9
z = -9
s = 9
>Exit code: 0    Time: 0.1301

...  and what is the issue in your opinion as I see none yet?

Why adding a forward zero changes the value of an expression?

[iamtheky]

why 0 -9 = -9  

because math.

[edzioedzio55]

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

[iamtheky]

because -3^2 = 9

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

[Jos]

Use this if you want the - to be last evaluated:

local $y = Execute("  - ($x^2)")

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

[edzioedzio55]

"z" should also be 9

[Jos]

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 )

[iamtheky]

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")

Just now, edzioedzio55 said:

No, as stated The formula evaluates to 0-9 in that case.

Jos

[edzioedzio55]

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.

[Jos]

Please post some code to demonstrate what you mean as I am not sure I understand that last post.

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.

Local $x = 3

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

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

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

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.
