Why aren't repeating decimals irrational but something like pi is?

We use closest representations for both of them, but they are not completely true.




227 and 3.14 are not exactly π but we use them as the best option available.



13 is 0.ˉ3 but that can be 0.333 or 0.333333 and these are not equal.



So why is one irrational and other is not?
