template<typename Char, typename Traits, typename Dimension, typename System> 
  std::basic_ostream< Char, Traits > & 
  operator<<(std::basic_ostream< Char, Traits > & os, 
             const unit< Dimension, System > & u);

Description

Print a unit as a list of base units and their exponents. for @c symbol_format outputs e.g. "m s^-1" or "J". for @c name_format outputs e.g. "meter second^-1" or "joule". for @c raw_format outputs e.g. "m s^-1" or "meter kilogram^2 second^-2". for @c typename_format outputs the typename itself (currently demangled only on GCC).
