Overview

HexCode

HexCodes are Code objects that are printed in hexadecimal. All of the attributes and methods of the Code class are applicable to HexCodes – the only differences are in to_s, which generates the string of digits used to print a number, and in the method that compares objects (Codes can only be compared to other Codes, HexCodes to other HexCodes).
