Ignoring the "float" vs "double" issue, you *do* realize that
4.88888 has no precise IEEE floating point representation, and thus
will never be *precisely* that value, right?

Even 0.1 has no precise representation... it has to be truncated to fit within
the 53(?) bits of precision.  So 0.1 added 10 times might not be precisely
1.0.  Most "flost to string" converters stop when they start getting into the
"imaginary noise" bits, and if you ask for a longer value, you'll get garbage.
