First, the limts of a number is the number self!

lim 0.(9)=0.(9)

Seconds:
If you come to zero from left (-x-axis) you will have a 0- limits
If you come to zero from right (+x-axis) you will have a 0+ limits
They are not the same things.

lim 1/x=0-
x-->-Infinty

lim 1/x=0+
x-->+infinity

That's right, but 0.(9) is the same as 1 even without limits. Both are a
representation of the same number in Arabic numerals.

It was what I tried to explain :)

Just curious,

Exactly how much memory you need in your PC to hold 0.(9) instead of 1.0 ?
