Use this decoder when the input is known to use the named encoding or classical cipher and you need to recover its bytes, symbols, numbers, or text deterministically.

Gray code

Required string input.

Decode a reflected binary Gray code back to its integer value. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Value

The resulting value returned as an integer.

• Decoding cannot reliably identify an unknown format or repair arbitrary corruption. Alphabet variants, padding, whitespace, character encodings, byte order, framing, cipher keys, and malformed-input policies must match the producer.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Confirm the format from metadata or a specification, preserve the original input, and validate decoded length or checksums where available. Treat decoded untrusted content as data rather than executable markup or code.

• Roman Numeral Decoder

  Decode a canonical subtractive Roman numeral between I and MMMCMXCIX into its integer value.

• Delta Decoder

  Reconstruct a numeric sequence from a first value and successive differences; floating-point rounding may appear in non-integer inputs.

• Zigzag Integer Decoder

  Decode zigzag (Protobuf varint signed) codes back to integers.
