Signed Integer Encoding Explorer
Compare two’s complement, one’s complement and sign-magnitude encodings, including range limits and negative-zero decoding.
Ready. Explore the example or use the input controls to begin.
Scope and practical limits
Widths 2–256 bits, up to 500 values. Encoding uses signed decimal; decoding uses binary patterns. Decimal -0 is encoded as ordinary zero. Out-of-range representations are identified individually.

Using Signed Integer Encoding Explorer
Compare two’s complement, one’s complement and sign-magnitude encodings, including range limits and negative-zero decoding.
- Start with the example and choose the declared input representation and any bit width.
- Change the operation or format, then inspect the precise result and validation messages.
- Copy the output or download text, JSON or a CSV audit. Save a project to retain editable inputs.
Example
At 8 bits, -5 is 11111011 in two’s complement, 11111010 in one’s complement and 10000101 in sign magnitude.
Questions & answers
Why is negative zero shown?
One’s complement and sign magnitude have distinct negative-zero bit patterns. Two’s complement has only one zero.
What are the limits?
Widths 2–256 bits, up to 500 values. Encoding uses signed decimal; decoding uses binary patterns. Decimal -0 is encoded as ordinary zero. Out-of-range representations are identified individually.
