static int floorDivisionWithLog2Divisor(int dividend, int log2Divisor) {
		return (dividend + (1 << log2Divisor) - 1) >> log2Divisor;
	}
Returns the value of the floor (greatest integer less than or equal to) of the result
 upon dividing the dividend by a divisor which is the power-of-two of the log2Divisor
@param dividend the dividend to the operator
@param log2Divisor the log2 of the intended divisor value
@return the floor of the division result
