In a logical left shift, the bits are shifted to the left by a specified number of positions. The bit (sign bit) is shifted out/discarded, and the vacant position on the is filled with a zero. Logical left shifts are primarily used for unsigned integer manipulation and simple bit operations.
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 left 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 1010 by 2^1 (2).
A logical shift is used in computing and digital systems for several purposes, primarily in operations. Logical shifts are used to manipulate individual bits in a binary number, such as clearing or setting specific . A logical left shift effectively multiplies a number by 2 for each shift position, while a logical right shift divides a number by 2 for each shift position (but without sign ).
