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.

Check whether this accu is able to return a result.

Always true here.

[inline, inherited]

Take as initialization the value t.

Dev note: this is a final method; override if needed by take_as_init_ (ending with '_').
