Some examples,

0.3 not recurring is 3/10

0.3 with one digit recurring is 1/3 (specify recurring Yes and recurring digits 1)

0.311 not recurring is 311/1000

0.301 with one digit recurring is 271/900 (specify recurring Yes and recurring digits 1)

0.301 with two digits recurring is 149/495 (specify recurring Yes and recurring digits 2)

0.142857142857 with six digits recurring is 1/7 (specify recurring Yes and recurring digits 6)

In the final example the 6 recurring digits are specified twice but this does not matter to the App. The excess digits are carefully removed and the calculation done with 0.142857
