I wrote my own desktop programming calculator that shows signed and unsigned decimal, octal, hexadecimal and binary at the same time. It also allows you to select 8-bit, 16-bit, 32-bit or 64-bit calculations, and do either signed extend (for converting from a lower bit to higher bit legnth) or zero extend. No floating point results though. It was a fun project to work on.
