The (0,1) range does have an infimum and a supremum.
You can't find an x such as (0,1) and (0,x] are the same set. If you could, there wouldn't any need of discriminate between "(" and "[" in the interval notation.
I knew you guys and gals would know the answer, and help me learn as well! I know I should crack a book and learn such things on my own. However, my time is limited and devoted to a different problem.
What I *should* have asked was:
Can I say that....
(0,1) is interchangeable with (1-1,1)
