I can't find the other thread.
But, 0.99 recurring does equal 1. I asked a Maths doctorate and he confirmed that although there are more convincing proofs and conjectures, this one below (Forgot who did it, but whoever it was, you're right):

Let's say .9 repeating is x and I'll will write as just .99R

Start:
.99R = x
9.99R = 10x
9.99R - .99R = 10x - x
9 = 9x
1 = x
x = .99R

THEREFORE, .99R is equal to 1!!!


Is actually quite sound.

I dare say, I'm a loser for not understanding the post is about. I didn't know basic maths could be so fascinating.
