The Calculator on this page will convert a proper fraction (e.g. 2/5)
to a decimal fraction (e.g. 2/5 = 0·4) or
vice-versa (e.g. 0.0625 is 1/16).
The decimal equivalents of fractions here
can be given to any number of decimal places, unlike an ordinary calculator which only gives
up to 10 or 12 decimal places.
The For Example: button will fill in the fraction input values in the calculator
for a decimal that has certain patterns in it digits:
e.g. the decimal which is the pattern of numbers from 0 upwards
with 2 digits each is 0·00 01 02 03 04 05 06 07 08 09 10 11 ...
is the decimal expansion of the fraction 1/9801.
Use the buttons to investigate the example.
The lower panel can tell you if a given fraction converts to either
a decimal that stops ("terminates" such as 2/5) or
to one which endlessly repeats a series of digits ("recurs" such as 2/3 = 0·666666...).
