Yes, writing a small percentage class ;) boost::lexical_cast is about
textual conversions, as performed by a standard stream with no special
formatting (with a special treatment, explained in the docs, for
string targets). "60%" is not a textual representation of a double in
the standard lib view of things, thus you have no luck with that; but
you can decide how *your classes* are streamed. Requirements indicated
here

<http://www.boost.org/libs/conversion/lexical_cast.htm#lexical_cast>

are to be fulfilled for the class to work with lexical_cast<>.
