Okay, i may be going crazy but slap this on frame one of a flash file and
observe the output:
//////////////////////////////////////////////////////////////////////////////////////////
var incrementNum:Number = 0;
var oldNum:Number = 0;
var resultNum:Number =0;
onEnterFrame = function(){gogo();}
function gogo()
{
oldNum = incrementNum;
incrementNum += 0.1;
resultNum = incrementNum - oldNum;
trace("old: "+oldNum);
trace("inc: "+incrementNum);
trace("res: "+resultNum);
trace("");
}
stop();
//////////////////////////////////////////////////////////////////////////////////////////
For those who dont have the time to test it the output follows like this:

so the res value continues on like that being 0.0999999999999996 rather than
0.1..
anyone have any idea why flash does this???
