Get off. One third is also written 1/3 and 0.333.... Actually, it's written 3 overbar, point three with the line over the repeating part instead of 0.33(3)....
Furthermore it is clear the exact value at a place of a rational number, to infinity.
Also for any irrational number as it is so defined, it is so.
