Yes, this is my exact understanding of the article too.

So in that case, "[it] allows representation of real numbers accurate to the last digit" doesn't really hold true.

I think you're reading it wrong. I think the intended meaning was that it's accurate for real numbers up to, but not including, the final digit"

That's how I read it.

Many real numbers have an infinite number of digits

I think you're missing the point. Using the example above. 1/3 has no final digit. 0.333333 repeating infinitely.

So how do you then store this number to the final digit or final -1 digit using this mechanism?
