Convert Decimal to Gray Code

Convert non-negative decimal integers to binary-reflected Gray code in your browser.

Tool workspace

Converts whole non-negative decimals to binary-reflected Gray code (max 256 bits). Nothing you paste is uploaded.

How it works

Enter a whole non-negative decimal number (0 or greater).

The tool converts it to unsigned binary, then applies binary-reflected Gray encoding (G = B XOR (B >> 1)). Results are capped at 256 bits—the same limit as sibling binary tools. Negatives, fractions, and oversize values are rejected with a clear message.

Everything runs in your browser. Nothing you paste is uploaded.

Examples

  • 0 → 0
  • 7 → 100
  • 13 → 1011
  • 255 → 10000000

FAQ

Is my number uploaded?

No. Conversion runs entirely in your browser. We do not log or store what you paste.

What is Gray code?

Binary-reflected Gray code encodes integers so successive values differ by only one bit. It is computed as G = B XOR (B >> 1) from the binary representation.

Why is there a 256-bit limit?

The limit matches sibling binary math tools and keeps results practical for browsers. Values that need more than 256 bits are rejected.
