Any number can be written in decimal form.
There are three different types of decimal number
- exact,
- recurring
- other decimals.
An exact or terminating decimal is one which does not go on forever, so you can write down all its digits. For example: 0.15
A recurring decimal is a decimal number which does go on forever, but where some of the digits are repeated over and over again. For example: 7.3333333333
Sometimes recurring decimals are written with a bar over the digits which are repeated, or with dots over the first and last digits that are repeated.
Other decimals are those which go on forever and don't have digits which repeat. For example pi = 3.141592653589793238462643...
