0.999... is just a label unfortunatly the context it try to label 1
expansion is just an approximation, change base.
0.3 in ternary is a correct label in fact it *is* 1 thus you are free
to write 0.3 or 1 in ternarys, this is not true for decimal
numbersystem 0.999... do not equal 1, because you can not create the
set that makes up 1 adding the members of the set ->
{0.9,0.09,0.009 ...}!= 1 there is no set at this form that equals 1,
but in ternarys we have no problem to write that the sum of members in
the set {0.1,0.1,0.1} = 1
