    Wouldn’t it be like 9.99 into infinity? 🤔 and since the human population (at least currently living) is not infinete, then at some 9.999999 there wouldn’t be anyone with a higher value? (I don’t know math)

        no, not really. In engineering math, sure but theoretical math it’s not

        • 0.999… = 1 in theory also.

          Otherwise, there exists a δ such that 1 - δ = 0.999…

          Then, the δ should have a first nonzero digit. Let us say it is in the millionth placd. But then, 0.999… cannot have a 9 in the millionth place.

          Even in theoretical math, 0.999 repeating ends up being exactly equal to 1. In fact, any terminating decimal can be rewritten in a similar manner. For example, 0.25 is exactly equal to 0.24999999 repeating

          It is in theoretical math as well. I just woke up and don’t know the proof by heart but there is a proof for 0.99 repeating being true equal to 1.
