Bob,  Thanks on that.  I see the use of the floor function.  This whole idea is trivial when one can use that.  What I am trying to do is basically do the floor function as a linear equation.  This is useful for pulling numbers apart.  Like a number 13.  How does one algebraically make it 1 and 3 or 10 and 3.  Either.
