Thanks Josh.
I kinda managed to get it working.
so for the records if someone else need it, it seems to work fine.
private function
safeBitCheck(num:Number,comparison:Number):Boolean
{
if(num < 2147483647 ) {
return (num & comparison)==comparison;
} else {
var binNumber:String = strrev(base_convert(num,10,2));
var binComparison:String =
strrev(base_convert(comparison,10,2));
for(var i:uint=0; i<binComparison.length; i++ ) {
if( binNumber.length < i ||
(binComparison.charAt(i)==="1"
&& binNumber.charAt(i)==="0") ) {
return false;
}
}
return true;
}
}
public function strrev(str:String):String {
return str.split("").reverse().join("");
}
public function base_convert(num:Number, frombase:Number,
tobase:Number):String {
return parseInt(num+'', frombase+0).toString(tobase+0);
}
