Abstract

A wide range of numbering systems is in use today, the most common being the decimal or denary system. This system utilises the ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. It is important to note that the first number is zero, and that the tenth number is nine. The total number of digits used in the system is known as the base or radix of the system; the radix of the decimal system is ten. A numbering system widely used in association with computers is the octal system which has a radix of eight and uses the eight characters 0, 1, 2, 3, 4, 5, 6, 7. Yet another system which is widely used in association with microprocessors is the hexadecimal system (abbreviated to hex) having a radix of sixteen.
