Bit-shifting is just multiplying and dividing by powers of two to add and remove digits. Left-shifting by n is multiplying by 2 n, and right-shifting is dividing by 2 n and flooring. Now if you're actually asking about arithmetic (i.e., signed) shifts, that goes a little farther.

Nettet2. aug. 2024 · The left shift by 2 places means multiplication by 4. The value of x after the two statements is 0’b0110. The left shift by one place can be interpreted as multiplication by 2.
