WebHere is a right arithmetic shift calculator. Enter a number to convert to 32 bit binary, plus the number of spaces to shift to the right, and the tool will return the result after the arithmetic shift. With an arithmetic shift, the sign of the number is preserved, see the right logical shift calculator to shift all digits and add leading zeroes. WebShifting right for a signed value (usually) propagates the sign bit. If you don't want to propagate the sign bit, use an unsigned value. – clstrfsck Aug 23, 2016 at 23:15 " For negative a, the value of a >> b is implementation-defined (in most implementations, this performs arithmetic right shift, so that the result remains negative)."

WebMay 11, 2010 · In an arithmetic shift, the sign bit is extended to preserve the signedness of the number. For example: -2 represented in 8 bits would be 11111110 (because the most significant bit has negative weight). Shifting it right one bit using arithmetic shift would give you 11111111, or -1.
