This is not the case.  10.0 is 8 * 1.25 or 2^3 * 1.01
						     [base 2].

                                         [P 1s]
In fact, all integers between zero and  1111...1
                                                [base 2]

(where P is the precision) are exactly representable in base 2 floating
point.  It is, however, the case that  N/10.0 is not necessarily the
same as 0.1*N when a binary floating point representation is used.
