A repeating or recurring decimal is a way of representing rational numbers in base 10 arithmetic. The decimal representation of a number is said to be repeating if it becomes periodic (repeating its values at regular intervals) and the infinitely-repeated portion is not zero. For example, the decimal representation of ⅓ becomes periodic just after the decimal point, repeating the single digit "3" for ever, i.e. 0.333…. A more complicated example is , whose decimal becomes periodic after the second digit following the decimal point and then repeats the sequence "144" for ever, i.e. 5.8144144144…. At present, there is no single universally accepted notation or phrasing for repeating decimals.
