Synopsis

// In header: <boost/accumulators/statistics/sum_kahan.hpp>

template<typename Sample, typename Tag> 
struct sum_kahan_impl {
  // types
  typedef Sample result_type;

  // construct/copy/destruct

};

Description

`sum_kahan_impl` public construct/copy/destruct

```
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

template<typename Args> void operator()(Args const & args);

```
result_type result(dont_care) const;
```
