## Calculating fractions with repeating decimals

My decimal to fraction calculator (featured in the third tab above) gives you the ability to enter repeating decimals by utilising the 'Number of trailing decimal places to repeat' box. To use it, simply enter the number of digits from the end of the decimal to repeat. For other non-repeating decimals, keep the default value at 0.

As an example, if you want to convert a repeating decimal such as 1.5476... then you should enter 1.5476 into the **Decimal** box and 4 into the **Number of trailing decimal places to repeat**
box (signifying that the last 4 digits of the number should repeat).
