GBase is a GTK program designed to convert between the four common bases used in
programming (decimal, hexadecimal, octal and binary). It converts numbers
on-the-fly as they are typed in. It can also convert numbers entered on the
command line. It can correctly handle both signed and unsigned 32-bit integers.
