In a logical left shift, the bits are shifted to the left by a specified number of positions. The bit ( bit) is shifted out/discarded, and the vacant position on the is filled with a . Logical left shifts are primarily used for integer manipulation and simple bit operations. For example, if you perform a left shift of 1 on the binary number , it becomes .
In a right shift operation, the bits of a binary number are shifted to the by a specified number of positions. Similar to left shifts, new bits are introduced on the side, and the rightmost bits are discarded. Each right shift effectively the number by 2 for each position shifted. For example, if you right-shift the binary number "1010" by one position, you get "0101," which is equivalent to dividing by (2).
Logical shifts are extensively used in computing and digital systems for several purposes. They play a crucial role in bit manipulation, where they are used to manipulate individual bits in a binary number, such as clearing or setting specific bits. A logical left shift effectively multiplies a number by for each shift position, while a logical right shift divides a number by for each shift position without sign extension.
