Detailed Description

template<class T>
struct xt::squared_norm_type< T >

Traits class for the result type of the norm_sq() function.

Member 'type' defines the result of norm_sq(t), where t is of type

Template Parameters

T.	It implements the following rules designed to minimize the potential for overflow:
T	is an arithmetic type: 'type' is the result type of t*t.
T	is a container of 'long double' elements: 'type' is long double.
T	is a container of another floating-point type: 'type' is double.
T	is a container of integer elements: 'type' is uint64_t.
T	is a container of some other type: 'type' is the element's squared norm type,

Containers are recognized by having an embedded typedef 'value_type'. To change the behavior for a case not covered here, specialize the traits_detail::norm_type_base template.
