namespace boost{ namespace multiprecision{ class tommath_int; typedef number<tommath_int > tom_int; }} // namespaces
Class template tommath_int
fulfils all of the requirements for a Backend
type. Its members and non-member functions are deliberately not documented:
these are considered implementation details that are subject to change.
The type of number_category<cpp_int<Args...> >::type
is std::integral_constant<int,
number_kind_integer>
.
More information on this type can be found in the tutorial.
