WebSimilarly when a number is pushed to the left by n bits means the number is multiplied by 2 power n. Eg. 25 << 1 = 50 (25 * 2 power 1) 25 << 3 = 200 (25 * 2 power 3) Thus in general if you shift a number to left by n bits, it gets multiplied n times by 2. The Bitwise right shift operator. The right shift operator shifts the bits towards the right.
