Bitshift left right problem

[ReFran]

Hi,

I need to translate a js example with bitshift left/right.

JS-Script:

var y = (((1 << 14) >> 1) - 1 - 5446);

WScript.echo(y);

the result is 2745.

Thanks in advance

BitShift()

doesn't work for you?

(hint ... click the name of the function)

Try this:

$x = BitShift(BitShift(1, -14), 1) -1 -5446

Try this:

#cs
JS-Script:
var y = (((1 << 14) >> 1) - 1 - 5446);
WScript.echo(y);

the result is 2745.
#ce

$y = BitShift(BitShift(1, -14), 1) - 1 - 5446
MsgBox(0, "Bitshit", $y)

Ok, so I used $x instead of $y

@JLogan3o13: indeed, I did the same thing as you already did...didn't saw your post!

I did try that, but didn't got the right result.

Many thanks for your help. I searched now tor 3 days how I can show a Yahoo map using Googles Map Api (the zoom factor and the y coord somewho revers). Finaly I found a phyton script which I translated - with some problems - to JS (for use in a html page). Now I want to use it also for my au3 map download tool. I tried already "$n = Bitshift(Bitshift(14,1),-1) -1 -5446", but didn't work correctly. So I thought before I spent further 3 day on a solution, here may be one who can solve it quicker.

So thank you very much for saving time and more endless testing. Works pefect.

@UEZ

Thanks for confirmation.

You are right I will take Y because it's the Y coord ;-)

best regards, Reinhard

A simplification (or anti-obscuration) of

BitShift(BitShift(1, -14), 1) - 1 - 5446

is

BitShift(1, -13) - 5447

ConsoleWrite(BitShift(BitShift(1, -14), 1) - 1 - 5446 & @LF)

; BitShift(BitShift(1, -14), 1) - 1 - 5446 = BitShift(1, -13) - 5447

ConsoleWrite(BitShift(1, -13) - 5447 & @LF)

#cs
    @ output console:-
    2745
    2745
#ce

Try this:

#cs
JS-Script:
var y = (((1 << 14) >> 1) - 1 - 5446);
WScript.echo(y);

the result is 2745.
#ce

$y = BitShift(BitShift(1, -14), 1) - 1 - 5446
MsgBox(0, "Bitshit", $y)

Lol. "MsgBox(0,"Bitshit",$y)" ... nice typo.

[UEZ]

That wasn't a typo...
