Detailed Description

template<typename T, typename S = typename mln::value::props< T >::sum, typename M = S>
struct mln::accu::stat::mean< T, S, M >

Generic mean accumulator class.

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

const [inline]

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 '_').

Reimplemented in mln::accu::stat::variance< T, S, R >.
