#3876 closed Bug (Fixed)

Hex Number Arithmetic is incorrect

Reported by: Zvend Owned by: Jon
Milestone: 3.3.16.1 Component: AutoIt
Version: 3.3.16.0 Severity: None
Keywords: Hex Number Arithmetic Cc: Melba23

Description

The hex arithmetic in the newest version broke compared to previous versions.

;~ AutoIt v3.3.14.5
Const $OFFSET = -0x46
Local $pSomePointer = Ptr(0x3100000 + $OFFSET)
ConsoleWrite("Pointer is: " & $pSomePointer & @CRLF)

Output:

Pointer is: 0x030FFFBA (Correct hex arithmetic)

;~ AutoIt v3.3.16.0
Const $OFFSET = -0x46
Local $pSomePointer = Ptr(0x3100000 + $OFFSET)
ConsoleWrite("Pointer is: " & $pSomePointer & @CRLF)

Output:

Pointer is: 0x03100046 (Incorrect hex arithmetic)

Hi I cannot answer this question as Jon will do it when It has time
in fact this pb come from a regression introduce by #3772 which will be fix by the fixing of #3869

Sorry for the trouble

Hello,

i found the same problem in all beta versions since 3.3.14.5, you can bypass them by wrote

Const $OFFSET = -(0x46)

thats only a bypass for hardcoded offsets. If you have functions where you dont know if the output value is supposed to be positive or negative this bypass wont work out. also that "solution" was mentioned in the link i provided
