No, there is only 1•1 which equals 1.

0.66 rounded to a whole number equals 1

Yes. The square of a whole number is always a whole number. For example, 3 squared is 9, so the square root of 9 is 3. What you never have, is the square root of a whole number being a fraction that is not a whole number. The square root of a whole number is either a whole number or an irrational number. For example, the square root of 2 is irrational, because there are no 2 whole numbers a and b such that a/b squared is 2. This is not terribly difficult to prove, but I have already said too much; I have answered your question.

No. 3/3 would be a whole, because 3/3 equals 1, and one is a whole number. If a number is over itself, it equals 1.
