Synopsis

// In header: <boost/units/lambda.hpp>

template<typename System, typename X, typename Y> 
struct plain_return_type_2<arithmetic_action< plus_action >, X, boost::units::quantity< BOOST_UNITS_DIMENSIONLESS_UNIT(System), Y >> {
  // types
  typedef boost::units::add_typeof_helper< X, boost::units::quantity< BOOST_UNITS_DIMENSIONLESS_UNIT(System), Y > >::type type;
};

Description

Partial specialization of return type trait for action X + quantity<dimensionless, Y>.
