quickbeam Posted July 11, 2017 Share Posted July 11, 2017 The BitShift funtion apparently does sign extension for 32-bit numbers if the MSb is set. Is there any way to turn that off and do real (C style) bit shifts? Link to comment Share on other sites More sharing options...
jchd Posted July 12, 2017 Share Posted July 12, 2017 BitShift in AutoIt is an arithmetic bit shift, not a logical operation. Help file should really say so and warn that BitShift may produce surprising result to unsuspecting users, e.g.: Local $i = 0xA0000000 Local $iSAR_1 = BitShift($i, -1) ConsoleWrite($i & @TAB & Hex($i) & @LF & $iSAR_1 & @TAB & Hex($iSAR_1) & @LF) This wonderful site allows debugging and testing regular expressions (many flavors available).

quickbeam Posted July 12, 2017 Author Share Posted July 12, 2017 (edited) Okay, thanks. I guess arithmetic and logical are better terms to describe it. I can see the value of both methods, but it did cause some debugging time. I guess I should have been tipped off when it said each bit shift is equivalent to doubling or halving the value. I'm going to write my own, hopefully that won't take too long. Edited July 12, 2017 by quickbeam Add sentence to first paragraph Link to comment Share on other sites More sharing options...
junkew Posted July 13, 2017 Share Posted July 13, 2017 Maybe with clr.au3 you can create objects like System.Numerics.BigInteger and on those you can do shift or you make a small c# class and compile that on the fly with clr.au3 FAQ 31 How to click some elements, FAQ 40 Test automation with AutoIt, Multithreading CLR .NET Powershell CMDLets Link to comment Share on other sites More sharing options...
