A geometric_distribution random number distribution produces integer values i≥0 distributed according to the discrete probability function
P(i|p)=p⋅(1−p)i.
template<class IntType = int>
class geometric_distribution {
public:
using result_type = IntType;
using param_type = unspecified;
explicit geometric_distribution(double p = 0.5);
explicit geometric_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);
double p() const;
param_type param() const;
void param(const param_type& parm);
result_type min() const;
result_type max() const;
};
explicit geometric_distribution(double p = 0.5);
Effects: Constructs a geometric_distribution object; p corresponds to the parameter of the distribution.
double p() const;
Returns: The value of the p parameter with which the object was constructed.
