I have been thinking about this quite a bit.  Maybe you could simulate this
by checking if there's a variance out to 1E-9 if it's that close to the
number then it is that number.  I was thinking alot about it because I was
wondering how my calculator does it.  It only carries out the 14th
significant digit.  Perhaps a subclass of float and int could do this?
