How it works
Values are handled as arbitrary-precision integers, so results are exact for any size. Underscores, spaces, and commas in the input are ignored. Choosing a fixed width shows the two's-complement bit pattern plus its signed and unsigned decimal meaning; values outside the width's range are rejected.
