Bitwise Calculator

About this calculator

This calculator computes the bitwise AND, OR and XOR of two integers by comparing them bit by bit in binary: AND returns a 1 only where both numbers have a 1 in that position, OR returns a 1 where either number does, and XOR (exclusive or) returns a 1 only where exactly one of the two does. These operations work on the raw binary representation of a number, not its decimal value, which is what makes them behave so differently from ordinary arithmetic.

Programmers use bitwise operations constantly for tasks like setting or checking individual flags packed into a single integer, working with permission bits, manipulating pixel colors in graphics code, and low-level performance tricks in embedded and systems programming. This calculator lets you verify the result of a bitwise expression by hand before or instead of running it in code.
