    What it means is that I need to pay a lot more attention to what I am
coding
I have apparently made MANY fumbles in the past few days.
NOW.......  Since I have tested and corrected the code.
Simply change
  floor(s)) = 1)
to
  floor(s)) = 0).

OR use the equal() command that was stated earlier.
You will find that only first example is and should be returned TRUE.
