Struct template make_unsigned

boost::random::traits::make_unsigned — Converts the argument type T to an unsigned type.


// In header: <boost/random/traits.hpp>

template<typename T> 
struct make_unsigned {


This trait has a single member type which is the unsigned type corresponding to T. Note that if T is signed, then member type should define a type with one more bit precision than T. For built-in types this trait defaults to boost::make_unsigned<T>::type. For user defined types it simply asserts that the argument type T is an unsigned integer (using std::numeric_limits). User defined specializations may be provided for other cases.
