Right Shift Operator (>>) with Signed vs. Unsigned Integers
Aspect | Signed Integers | Unsigned Integers |
---|---|---|
Sign Bit Preservation | Sign bit is preserved, replicated to fill vacant leftmost positions. | No sign bit, all bits are shifted to the right, filling vacant positions with zeros. |
Example | -8 >> 1 results in -4 (Binary: 1111 1100 ) | 8 >> 1 results in 4 (Binary: 0000 0100 ) |
Division by Powers of 2 | Right shift performs signed division by 2^n . | Right shift performs unsigned division by 2^n . |
Implementation in Programming | Behavior depends on language and compiler. Most use arithmetic right shift. | Always performs logical right shift. |
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.
