10188,Loses floating point precision on round trip,Magne OEstlyngen <magne+boost@…>,Sebastian Redl,"ptrees stream_translator uses a precision of std::numeric_limits<F>::digits10 + 1 when converting floating point values.  This is not always enough, and a more correct value would be digits10+2 or max_digits10 (c++11 only). See ticket:9177 for a similar issue.
