## Public Types

using type = decltype(std::declval< T >() *std::declval< U >())

## Detailed Description

template<typename T, typename U>
struct internal::ProductTypeImpl< T, U >

A struct that implements the default product type resulting from the multiplication of two types.

Note
Care should be taken when T or U have qualifiers (const or volatile) or are lvalue or rvalue references! It is recommended that specialization of this class is only made for unqualified (fully stripped) types and that the ProductType class be used to determine the result of operating with (potentially) qualified types.
