It is 0.999... which is under discussion.
And it means the same as Sum_(n= 1...oo) 9/10^n
Which is a convergent infinite series in proper mathematics And only nonsense to those without sense.

0.999... means Sum_(n= 1...oo) 9/10^n
or equivalently, 9*Sum_(n= 1...oo) r^n, where r = 1/10.
It is well known among mathematicians that for every r strictly between 1 and +1, Sum_(n= 1...oo) r^n = r/(1r)
Thus for r = 1/10, the sum is (1/10)/(11/10) = 1/(10  1) = 1/9
So it is clear that the one cell of "spermatozon" is not a brain cell.
