Appendix A
Number systems
A.1. Overview
The efficient use of a microprocessor or microcontroller requires a working knowledge of binary, decimal, and hexadecimal numbering systems. This section provides a background for those who are unfamiliar with these numbering systems and who do not know how to convert from one number system to another one.
Number systems are classified according to their bases. The numbering system used in everyday life is base 10 or the decimal number system. The most commonly used numbering system in microprocessor and microcontroller applications is base 16, or hexadecimal. In addition, base 2 (binary) or base 8 (or octal) number systems are also used.
