Is a non-repeating and non-terminating decimal always an irrational?

We can build 1/33 like this, .030303..... (03 repeats). .030303.... tends to 1/33 .
So,I was wondering this: In the decimal representation, if we start writing the 10 numerals in such a way that the decimal portion never ends and never repeats; then am I getting closer and closer to some irrational number?

hi Reek

Yes.

Terminating decimals can be converted to fractions.

Recurring decimals can be converted to fractions.

All the rest are irrational.
