Boost.Random Support

#include <boost/int128/random.hpp>

Including this header specializes the traits that Boost.Random uses to reason about integer types, so that int128_t and uint128_t can be used directly with the Boost.Random engines and distributions (for example boost::random::uniform_int_distribution). This header requires Boost.Random to be available.

The following specializations are provided in namespace boost::random::traits for both int128_t and uint128_t:

Trait Purpose

Trait	Purpose
`is_integral`	Reports both types as integral.
`is_signed`	Reports `int128_t` as signed and `uint128_t` as unsigned.
`make_unsigned`, `make_unsigned_imp`	Provide the unsigned type mapping Boost.Random uses when generating values.
`make_unsigned_or_unbounded`, `make_unsigned_or_unbounded_imp`	Provide the unsigned-or-unbounded type mapping Boost.Random uses.

is_integral

Reports both types as integral.

is_signed

Reports int128_t as signed and uint128_t as unsigned.

make_unsigned, make_unsigned_imp

Provide the unsigned type mapping Boost.Random uses when generating values.

make_unsigned_or_unbounded, make_unsigned_or_unbounded_imp

Provide the unsigned-or-unbounded type mapping Boost.Random uses.

These specializations live in boost::random::traits, not boost::int128.

An example combining Boost.Random with the library types is available on the examples page.
