(adsbygoogle = window.adsbygoogle || []).push({}); Meh, this is a class I've had for a while now, added like 2 things today but I just thought it would be useful to some people. Btw, the 'Quick' functions are all much much faster than the corresponding Math.Whatever function. Just saying.

            data &= ~(1 << position);

        public static int QuickCeiling(double x)

        {

            return QuickFloor(x + 1);

        }



        public static double QuickRound(float d)

        {

            return (d - (int)d) < .5 ? 

                (int)d | 0 : 

                (int)(d + 1) | 0 ;

        }



        public static double QuickRound(double d)

        {

                (int)d | 0 : 

                (int)(d + 1) | 0 ;

        }

    }

}

Fixed round function.
