Binary and decimal do not cover the entire space of possibilities.  The
problem is not in conversion to a text form, it's in base conversion.  If
you are willing to assume that floating point is binary, it's conceivable
to convert floating point to octal or hex rather than decimal.

Also, if you have well-behaved (IEEE) floating point conversions, and allow
enough digits, you may not have roundoff errors.
