Base class for the helper class to deduce properties of numeric types defined in this API.
This class provides the common default implementations of all member of numeric_traits
, for its default template as well as all specialization. Thus, specializations just have to redefine what changes.
The default uses default constructed values. It therefore requires that a value of T
can be default constructed.
