Detailed Description

template<typename T, typename S = typename mln::value::props< T >::sum>
struct mln::accu::math::sum< T, S >

Generic sum accumulator class.

Parameter T is the type of values that we sum. Parameter S is the type to store the value sum; the default type of S is the summation type (property) of T.
