How to use this tool
- Choose Width, Operand admission and Operation. Enter Operand A and Operand B only when the selected operation uses it.
- Enter Count for shifts/rotations. Counts at least the width zero/sign-fill shifts; rotations reduce count modulo width.
- Select Calculate bitwise result and download bitwise-result.json. Unused operand/count fields are ignored by the operation.
Examples
Signed 8-bit -128 arithmetic-right by 1 yields signed -64, unsigned 192, binary 11000000 and hex c0.
Limitations
- Widths 8,16,32,64,128 or 256 bits; operands at most 100 decimal digits and within selected range; count0–256; 64 KiB JSON and 30 seconds.
- No hexadecimal operands, fractions, exponent notation, arbitrary expressions or unbounded shifts.
- Arithmetic right shift interprets the current-width two-complement sign even when operand admission is unsigned. Finite calculations have no artificial long-running workload claim.
