|For power operation, multiplication is done repeatedly the same number of time as is the number. Direct bitwise operation for power is not available.|

|Multiplying by a power of 2 is the same as shifting to the left. If you shift it left by 3 places you multiply it by 2^3=8. Similarly shifting to the right is division by powers of 2.|
