Prefixes 0b, 0o, and 0x are accepted where a field says “integer”. Underscores and visual spacing are ignored where appropriate. Your values stay in this browser.

What is XNOR?

XNOR produces 1 where aligned bits agree.

Use it as a fixed-width equality mask.

The rule

Read the representation exactly

What the bits are doing

Worked interpretation

Read the result in context

XNOR=NOT(XOR)

Interpret with care

Important boundary

The resulting agreement bits are not a single whole-word equality verdict by themselves.

For a small base-two example, use the Binary Calculator.

Quick guide

How to use this calculator

  1. Choose the direction, operation, representation, or parity convention when one is provided.
  2. Enter the labelled values and an explicit word size, base, polynomial, or encoding option where required.
  3. Read the primary result together with its alternate representations and stated convention.

Calculation method

Apply the declared binary rule

XNOR = NOT(A XOR B), limited to the selected width.

The calculator validates every digit against its numeral base, keeps integer and bitwise work exact with arbitrary-precision integers, and limits fixed-width operations to the selected word.

Worked example

Worked binary example

In four bits, 1010 XNOR 1100 = 1001.

XNOR = NOT(A XOR B), limited to the selected width.

Supported inputs

Precision and limits

Input interpretation

Binary-only fields accept 0 and 1. General integer fields accept decimal plus 0b, 0o, or 0x prefixes. Base conversion supports bases 2 through 36.

Word size and output

Most fixed-width tools support 1–256 bits. Results expose signedness, truncation, parity, or encoding conventions whenever those choices change the meaning.
