Interesting.  My calculator (a Sharp EL-512 II) gives virtually the same
erroneous square root as Excel!  That is, the square root of .999975 is
given as .999987499.  It looks like this problem is not unique to Excel;
to make its way into the entirely silicon brain of my calculator this error
must be the result of an ancient and honorable (although badly conditioned)
numerics routine...
