Struct template sum_kahan_impl



// In header: <boost/accumulators/statistics_fwd.hpp>

template<typename Sample, typename Tag> 
struct sum_kahan_impl : public accumulator_base {
  // construct/copy/destruct
  template<typename Args> sum_kahan_impl(Args const &);

  // public member functions
  template<typename Args> void operator()(Args const &);
  result_type result(dont_care) const;


sum_kahan_impl public construct/copy/destruct

  1. template<typename Args> sum_kahan_impl(Args const & args);
    Kahan summation algorithm.

    The Kahan summation algorithm reduces the numerical error obtained with standard sequential sum.

sum_kahan_impl public member functions

  1. template<typename Args> void operator()(Args const & args);
  2. result_type result(dont_care) const;
