Repeating decimal

A repeating decimal is a rational number with a fractional part that has a period with digits that are repeated infinitely.

Pure repeating decimal

Just after the decimal point there are one or more digits that are repeated.
Example: 0.777... = 0.7

Mixed repeating decimal

After the decimal point are one or more digits that are not repeated, followed by one or more digits that are repeated.
Example: 1.91222... = 1.912 , where 91 are the digits that are not repeated and 2... are the digit that is repeated.
