0.999999... = 1?

What the fuck. Why is that true. They got different numbers in them.

It was said earlier that 0.999~=1 because there are no other real numbers between it and 1.
in that case 0.999~8=0.999~=1
then 0.999~7=0.999~8=0.999~=1

however we know that there are real numbers between 0.999~7 and 1, hell i wrote 2 of them down.
the fact that there are no real numbers between 0.999~ and 1 does not mean they are the same.
