Non Terminating Decimals
There are many decimal fractions in which the number of digits after its decimal point is
unlimited, again one or more than one digit does not occur repeatedly. Such decimal
fractions are called non-terminating decimal fractions, For example,
5.134248513942307 ............ is a non-terminating decimal number. The square root of 2
is a non terminating decimal. Now we want to find the square root of 2.
