How This Bitwise Calculator Works
This bitwise calculator takes two values, A and B, in whichever base you enter them, and computes every common bitwise operator against them at once. As a bitwise and or xor calculator it doesn't make you pick a single operator ahead of time, every result, from AND through the bit shifts, updates together so you can compare them side by side in decimal, binary, hex, and octal.
Eight Bitwise Operations Plus Shifts
AND, OR, and XOR are the three foundational bitwise operators, this xor calculator online shows all three together with their negated counterparts NAND, NOR, and XNOR. NOT A and NOT B flip every bit of a single value independently. Left shift and right shift move every bit position left or right by B places, this bit shift calculator automatically keeps the shift amount within the selected word size so an oversized B still produces a well-defined result.
Understanding Signed vs. Unsigned Representation and Word Size
Every result is computed within a fixed word size, 8, 16, 32, or 64 bits, which determines both how many bits are shown and how negative numbers are represented. This two's complement calculator displays decimal results using standard two's complement: if the highest bit is set, the value is interpreted as negative, exactly how signed integers work in most programming languages, while the binary, hex, and octal columns always show the raw unsigned bit pattern.
Common Uses
Working with bit flags and permission masks, debugging low-level code that manipulates individual bits, and verifying a bitwise operator calculator result while learning digital logic or preparing for a systems programming interview are the most common uses. Combining RGB color channels, working with network subnet masks, and general curiosity about how a specific bitwise operation behaves at the bit level are common secondary uses.
What This Tool Doesn't Do
This tool always computes both operands and every operator together, it doesn't support chaining more than two values or building a multi-step bitwise expression, for that use a general math expression evaluator instead. Values are also masked to the selected word size, so a very large input effectively wraps around (only the lowest N bits are kept), matching how bitwise operations behave in most programming languages rather than preserving arbitrary precision.
