Logical Right Shift
Bitwise logical right shift refers to the operation of shifting the bits of a binary number to the right by a specified number of positions while filling the vacant leftmost positions with zeros. This operation is commonly used with unsigned integers and is denoted by the >>
operator in most programming languages.
Syntax:
operand >> n
Where operand
is the value whose bits are to be shifted, and n
is the number of positions to shift by.
Example:
# Logical right shift
x = 8 # Binary: 0000 1000
y = x >> 1 # Binary: 0000 0100, Decimal: 4
Use Cases:
- Unsigned Integer Division by Powers of 2: Logical right shift can be used to divide unsigned integers by powers of 2 efficiently.
- Clearing Bits: Logical right shift is useful for clearing specific bits in a binary number, as shifting bits to the right fills the vacant leftmost positions with zeros.
Right Shift Operator (>>) in Programming
Right shift operator (>>), commonly found in programming languages, including C, C++, Java, and others, is used to shift the bits of a number to the right by a specified number of positions. Each shift moves all bits in the operand to the right by the number of positions indicated by the right operand.
