What is Bitwise Calculator?

Perform bitwise operations on numbers with an interactive visual bit grid.

Calculate AND, OR, XOR, NOT, NAND, NOR, XNOR, left shift, right shift, and unsigned right shift. Enter values in decimal, hex, octal, or binary. Toggle individual bits by clicking. See results in all number bases simultaneously. Supports 8, 16, 32, and 64-bit modes with two's complement signed interpretation. Includes a truth table generator, common bit mask library, and Unix-style flag permission calculator. All calculations run locally in your browser.

How to Use Bitwise Calculator

1Enter two numbers (A and B) using the input fields - select decimal, hex, octal, or binary input
2View all bitwise operation results instantly in the results grid
3Click bits in the interactive bit grid to toggle them and see values update
4Use the truth table generator or flag calculator for additional analysis

Frequently Asked Questions

What bitwise operations are supported?

AND, OR, XOR, NOT (for both inputs), Left Shift, Arithmetic Right Shift, Unsigned Right Shift, NAND, NOR, and XNOR. Shift operations use a configurable shift amount.

Can I click individual bits?

Yes. The interactive bit grid lets you click any bit to toggle it between 0 and 1. The corresponding number value updates in real time across all bases.

What bit widths are supported?

8-bit, 16-bit, 32-bit, and 64-bit modes. The bit grid, value range, and two's complement interpretation all adjust to the selected width.

Does it show results in multiple bases?

Yes. Every result is displayed simultaneously in decimal, hexadecimal, octal, and binary, plus the signed two's complement interpretation.

How does the calculator handle negative numbers?

Negative values use two's complement at the selected bit width. The most significant bit acts as the sign bit, and the tool shows both the unsigned and signed interpretation so you can see exactly how the bit pattern maps to a value.

Can I enter values in hex or binary instead of decimal?

Yes. Each input field lets you choose decimal, hexadecimal, octal, or binary. You can mix bases between the two operands, and every result is shown across all four bases at once.
