Introduction

The binary number system is the most important one in digital systems, but several others are also important. The decimal system is important because it is universial used to represent quantites outside a digital system. This means that there will be situations where decimal values have to be converted to binary values before they are entered into the digital system.

In additional to binary ans decimal, two other number systems find wide-spread applications in digital systems. The octal (base-8) and hexadecimal (base-16) number systems are both used for the same purpose- to provide an efficient means for representing large binary system.

This chapter will show you how to perform these conversions.
