Chapter 9
Logic and numbering systems
Abstract
This chapter introduces the concept of Boolean algebra and the different logical operators that are used to describe logical relations. Then it describes the different numbering systems that make up polynomial systems, namely binary, octal, hexadecimal, and decimal. This is followed by a discussion on multibyte integers, the computing methods used to represent signed and unsigned integers, and floating point. The use of the Binary Coded Decimal as an alternative means of representing decimal numbers is then presented. The chapter concludes with discussions on single- and multibyte characters, namely ASCII and Unicode, respectively.
