A decimal can be both rational and irrational.

Rational decimals are 0.25 , 0.234234234..., because they can be converted to a fraction.

However, irrational decimals , such as pi = 3.141592.... cannot be converted to a equal fraction.

A rational decimal are where the digits regularly repeat, and go to infinity, such as 0.234234234...

However, irrational decimals, such as pi = 3.141592... were the digits go to infinity but there is no regular repetition of the numbers.

Some other irrational decimals are the square roots of prime numbers. ;_

sqrt(2) = 1.414213562...

sqrt(3) = 1.732050808...

sqrt(5) = 2.236067978....
