Hello, can you please provide the << and >> operators for boost::multiprecision::number as a stream template?

currently (fixed ostream) template std::ostream& operator<<(std::ostream& os, const number&)

useful template std::basic_ostream& operator<<(std::basic_ostream& stream, const number&)

I dodged that when first writing multiprecision because some backends (all those that are external C libraries) have narrow character conversions only.

So far - and somewhat to my surprise - not one person has requested template iostream operators.  Do you have a concrete use case?

Best, John.

My game is called "Compatibility" :-) thx Gero
