How to use

  1. 1 Enter operands A and B in any base — prefix with 0b, 0o, 0x or paste decimal.
  2. 2 Pick an operation (AND / OR / XOR / NAND / NOR / XNOR / NOT / shifts).
  3. 3 Choose a bit width (8/16/32/64) for masked arithmetic, or Unbounded for raw BigInt.
  4. 4 Result is shown in all four bases at once. Copy the decimal form with one click.

Why use this tool

  • Nine operations including unsigned right shift (>>>) synthesised for BigInt.
  • Bit-width masking matches what a C / Rust / Java compiler would do.
  • Dec / Bin / Oct / Hex shown side-by-side for A, B and result.
  • Pure browser logic, zero dependencies.

Frequently asked questions

What is the difference between >> and >>>?

>> preserves the sign bit (arithmetic shift). >>> shifts in zeros from the left (logical shift). On a fixed bit-width the difference matters; on unbounded BigInt the two collapse to the same operation for non-negative values.

Why does NOT 12 give -13 in unbounded mode?

BigInt uses two's-complement of an infinite-width integer. ~12 = -13. Switch to 32-bit width to see the masked result fffffff3.

How are NAND / NOR / XNOR computed?

They are AND / OR / XOR followed by a bitwise NOT, then masked to the selected width.

What is Bitwise Calculator?

A Bitwise Calculator is a tool that performs bit-level operations on two operands directly in the browser. It supports AND, OR, XOR, NAND, NOR, XNOR, NOT, and shift operations, computing on BigInt values to handle large numbers, and displays each result simultaneously in decimal, binary, octal, and hexadecimal for easy inspection of the bit patterns.

Features

Full operator set

AND, OR, XOR, NAND, NOR, XNOR, NOT, and left/right shifts.

Every base at once

See each result simultaneously in decimal, binary, octal, and hex.

BigInt-safe

Operates on arbitrarily large integers without floating-point loss.

Example

Input

A = 12, B = 10

Output

AND (&):  8
OR  (|):  14
XOR (^):  6

Common use cases

  1. 1

    Work with bit flags

    Combine (OR) or test (AND) permission and feature flags.

  2. 2

    Compute masks & shifts

    Build bitmasks and check the effect of << and >> on a value.

  3. 3

    Learn bit manipulation

    Watch the binary result change per operation to build intuition.

Summary

Zerethon's bitwise calculator performs AND, OR, XOR, NAND, NOR, XNOR, NOT, and shift operations on two BigInt operands in your browser, showing each result in decimal, binary, octal, and hex at once. It works on arbitrarily large integers with no precision loss. Nothing is uploaded.
