But it is well defined.  The number of decimal digits printed should
be just enough so that I can eval() it to get exactly the same binary
representation that I started with.  If your home computer uses the
same internal binary format for floating point, then it should be able
to read it exactly as well.  (If these two machines use different
binary formats then lossless conversion will not be possible.)
