26.6.8.2.1 Class template uniform_int_distribution [rand.dist.uni.int]

A uniform_int_distribution random number distribution produces random integers i,, distributed according to the constant discrete probability function

template class uniform_int_distribution { public:

using result_type = IntType;
using param_type  = unspecified;


uniform_int_distribution() : uniform_int_distribution(0) {}
explicit uniform_int_distribution(IntType a, IntType b = numeric_limits<IntType>::max());
explicit uniform_int_distribution(const param_type& parm);
void reset();


template<class URBG>
  result_type operator()(URBG& g);
template<class URBG>
  result_type operator()(URBG& g, const param_type& parm);


result_type a() const;
result_type b() const;
param_type param() const;
void param(const param_type& parm);
result_type min() const;
result_type max() const;

};

explicit uniform_int_distribution(IntType a, IntType b = numeric_limits<IntType>::max());

Remarks: a and b correspond to the respective parameters of the distribution.

Returns:The value of the a parameter with which the object was constructed.
