Wherever you decide to stop the repeating decimal, you need to round the last digit up to 7.

True if I were to round it, but I was trying to imply an infinite number of digits. But this does bring up the question of whether that infinite digit should be a 7. Possibly it should.

No, the infinitely repeating digit cannot be a 7. That would have a very different value than a repeating 6.
.6666666.... equals six ninths (= 2/3) .777777777.... equals seven ninths, because .111111111.... equals one ninth.

I did not mean to imply that the repeating digit would would be 7, but that possibly the very last digit out at infinity might be considered to be 7, but there really is no last digit there is always one further out.

IDR, and I do need refreshers on occasion, but wasn’t this taught back in the 3rd or 4th grade?

If there are an infinite number of significant places (digits), then is there ever a least significant digit? I don't need a response. This is for philosophy students to consider.

My son, who is a computer/network tech has a t-shirt that reads: "My password is the last 8 digits of pi."

What are those digits? Does anyone give him an answer? Another one for the philosophers.

Sorry for the misspelling of your name. K and L are next door, and I did not catch it. I try to proofread, but I am not good at it, and too many things slip thru. It gets worse when trying to figure out whether I said what I thought I was saying.
