19.3 Octal numbers

(a) Introduction

The octal system has a base of eight, and uses the digits 0 to 7. It is

important in digital work. The conversion of denary to octal and

octal to denary for both integers and fractions follows the rules

given in Section 19.1. It will be shown later in this section that large

denary numbers are more easily converted to binary if the numbers

are first converted to octal and then to binary.
