recurring decimal
A recurring decimal is a decimal fraction which has an infinite number of digits.
An example is , as = 0.33333…
We can see that the number 3 goes on and on. This is shown by placing a dot over the repeating digit, like this:
Another example is , as = 0.142857142…
In this example, a block of numbers, namely 142857, repeats forever. When this happens, a dot is placed over the first repeating digit and the last repeating digit in the block, like this:
The opposite of recurring decimal is terminating decimal.
