What is XNOR Calculator?

XNOR Calculator computes the bitwise XNOR (exclusive NOR) — the inverse of XOR. A bit in the output is 1 when both corresponding input bits are the same (both 0 or both 1), and 0 when they differ. XNOR is used in equality comparisons, error detection, and digital circuit design.

How to Use XNOR Calculator

1

Select input base.

2

Enter two numbers.

3

The XNOR result appears in all bases.

Common Use Cases

  • Checking bit equality between two values.
  • Implementing comparator circuits.
  • Error detection in digital logic designs.

Example Input and Output

12 XNOR 10 (decimal).

A=12, B=10
A: 12 (1100₂)
B: 10 (1010₂)
XNOR result
XNOR: 4294967289 (11111111111111111111111111111001₂)

Frequently Asked Questions

What is the difference between XNOR and XOR?

XOR outputs 1 when bits differ, 0 when they match. XNOR is the inverse — outputs 1 when bits are the same, 0 when they differ.
