[boost] stream operators for number

Hello, can you please provide the << and >> operators for boost::multiprecision::number as a stream template? currently (fixed ostream) template <class Backend, expression_template_option ExpressionTemplates> std::ostream& operator<<(std::ostream& os, const number<Backend, ExpressionTemplates>&) useful template <typename Char, typename Traits, typename Backend, expression_template_option ExpressionTemplates> std::basic_ostream<Char, Traits>& operator<<(std::basic_ostream<Char, Traits>& stream, const number<Backend, ExpressionTemplates>&) thx Gero
