WebShifting right by n bits on a two's complement signed binary number has the effect of dividing it by 2 n, but it always rounds down (towards negative infinity). This is different from the way rounding is usually done in signed integer division (which rounds towards 0). This discrepancy has led to bugs in a number of compilers. [8] WebWhen shifting right with an arithmetic right shift, the least-significant bit is lost and the most-significant bit is copied.
