This will force all bits after the
first 8 to be discarded:
AND OR XOR

You then simply shift the original value to the right by 8 bits and repeat for the next value. Applying this
to your original problem, your class might look like this:
class ShiftBits
{
public static function main()
{
var newInt:Int;
newInt = 155 + (80 < < 8) + (17 < < 16) + (131 < < 24);
trace(newInt & 255);
trace(newInt > > 8 & 255);
trace(newInt > > 16 & 255);
trace(newInt > > 24 & 255);
}
}
Try compiling this program and see for yourself.
The Math Class
Don ??™ t panic; it is not a discussion about school here. However, you have been looking at number values,
so sooner or later, you must start doing some math with your values.
