Repeating Decimals

Repeating decimals are numbers whose decimal parts are composed of infinitely-repeating sequences of digits. Such numbers are always rational and can therefore be converted into fractions. Wolfram|Alpha can be used to convert between fractional and repeating decimal representations and to analyze or perform computations with these numbers.
Repeating Decimals

Find fractional representations of repeating decimals. Generate repeating decimals by specifying their digits.

Compute the exact value of a repeating decimal:

.333...
.142857...
.03571428571428...

Specify the digits to repeat:

.1234 with the last 2 digits repeating
.999 with 123 repeating

Do calculations with repeating decimals:

.999... = 1
13 * 0.076923..
(0.8333...)(0.1111...)/(0.22111111...)
Sin[.123451234...]
