Actionscript 3 :: Turn Negative Number To Positive With Bitwise Operations?
Jul 16, 2011Is there a direct way how to turn a negative number to positive using bitwise operations in Actionscript 3? I just think I've read somewhere that it is possible and faster than using Math.abs() or multiplying by -1. Or am I wrong and it was a dream after day long learning about bytes and bitwise operations?
What I saw was that bitwise NOT almost does the trick:
// outputs: 449
trace( ~(-450) );
If anyone find this question and is interested - in 5 million iterations ~(x) + 1 is 50% faster than Math.abs(x).
Flex :: Bitwise Operations Without Bitwise Operators?
Sep 19, 2009Here's an example I ran across:
private function bitwiseAnd(a:int, b:int):int {
var result:int = 0;
var n:int = 1;[code]....
So basically all I need then is bitwiseOr and bitwiseNot and I'm set.The reason is that Pixel Bender doesn't support bitwise ops (inexplicably) but does support various math operations. Also they don't support loops for Flash either, but the above can just be expanded out.I thought about doing bitwise ops without bitwise operators a while back, but couldn't picture how to do it. I wouldn't know how the above was derived logically either.
Flash :: Bitwise-shift Operations In AGAL?
Jan 18, 2012If I encode all colors into one single float value (RGB) as:

How can I retrieve those color channels back in AGAL? There doesn't seem to be any bitwise operators.
ActionScript 3.0 :: Number Operations - Multiply 17.4*32.8 The Result Is 570.7199999999999?
Feb 13, 2011I am working on a project where I need a lot of calculations.I found a really strange and very annoying problem in Flash: If you try to multiply 17.4*32.8 the result is 570.7199999999999 !!! This is just a single example.In this way my application looks buggy sometimes. What's the reason for this wrong result?In my application I don't want to round the numbers .

ActionScript 2.0 :: What Are Bitwise Operators And How/why Do You Use Them?
Nov 19, 2004i came across these things called bitwise operators. After some research i didnt get any further than the fact that they alter bits directly. Then i read something on shifting bits and stuff, and that this would be more efficient it this got me confused. Can you use them to optimize your code? Can someone give some examples of this, like a function and his alternative (using bitwise operators)?

View 0 RepliesActionScript 2.0 :: Casting String Gotten From Xml To A Number Type?
May 1, 2007I have parsed the data from an xml doc to global vars in flash and need to use a few of them as numbers for things the position of "nodes" on the screen. However I can not cast the data stored as a var to a number or int value.
For example in the code below when the set Node button is pressed it traces the "Node's" current X value, then the value in the global var gotten from the xml, which contains the x position of where to place the Node.
Next it creates a new var of Number Type and assigns it the Number value of the string in global var. It then traces the new value of SNtopLeftX and sets the x pos of the Node's movie clip to the value of SNtopLeftX However the Node doesn't move and this is the output I get from the traces
Start Node is at x = -734.5
nod_topLeftX is 16
TopLeftX = 16
SN TopLeftX = NaN
I do not understand why I am getting NaN when the string of nod_topLefX is 16, any ideas?
------------------------------------------------------------------------------------------------------------------- This is my Code
butNodeSet.onRelease = function() {
trace ("Start Node is at x = " + mcStartNode._x);
trace ("nod_topLeftX is " + nod_topLeftX);

ActionScript 2.0 :: Additions Of The Number Data Type?
May 1, 2008I'm trying to get the sum of two number values in an XML file, so I'm doing this:
PHP Code:
_root.gallery_height = myGalleryXML.firstChild.attributes.height; // '200'
_root.spacing = myGalleryXML.firstChild.attributes.vertical_spacing; // '20'
_root.bar_y= _root.gallery_height+_root.spacing;
trace(_root.bar_y); //outputs 20020
The answer is supposed to be 220, but it comes out at as 20020 because the interpreter treats then as strings.
I can fix the problem by casting the type using the Number() method this way:
PHP Code:
_root.gallery_height = myGalleryXML.firstChild.attributes.height; // '200'
_root.spacing = myGalleryXML.firstChild.attributes.vertical_spacing; // '20'
_root.bar_y= Number(_root.gallery_height)+Number(_root.spacing);
trace(_root.bar_y); //outputs 220
This works fine, but is it *the right* way of doing it? Why is Flash treating my numbers as strings?

ActionScript 3.0 :: Converting Grayscale Bitmap To Alpha Bitwise Stuff
Sep 11, 2009I've written a function that makes all white pixels in an image transparent. This works OK, but the resulting image looks jagged because it only replaces pixels that are solid white. What I'd really like to do is set the alpha value for each pixel proportional to the amount of white in that pixel, then set the RGB value to #000000. I think this would produce a very smooth semi-transparent image. However, I'm not very good at bitwise operations. Can any of you lend a hand?
As an added bonus I'd like to overlay the resulting bitmap on top of another image. I know this is possible via other means, but it would be nice to do it all in one function for performance reasons and simplicity.
