I am trying to multiply to number type variables: The code is something like this::
trace(6.60*6);// !=39.6
var a:Number=6.6;
var b:Number=6;
trace(a*b);// !=39.6
it is not equal to 39.6 in Action Script 3.0 .. instead showing 39.5999999994…
This is a by product of IEEE standard of floating point arithmetic. If you want the real reason why check this paper:
http://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html
Most of this comes from Actionscript’s Javascript roots, and in Javascript everything is floating point. There is no diference between ints and floating point math so strange errors crop up that don’t crop up in other languages, but they would if you alway used floats.
