lognormal_distribution Class

Generates a log-normal distribution.

 class lognormal_distribution {
public:
 typedef RealType result_type;
 struct param_type;
 explicit lognormal_distribution(result_type m0 = result_type(0.0),
 result_type s0 = result_type(1.0));
 explicit lognormal_distribution(const param_type& par0);
 result_type m() const;
 result_type s() const;
 param_type param() const;
 void param(const param_type& par0);
 result_type min() const;
 result_type max() const;
 void reset();
 template<class Engine>
 result_type operator()(Engine& eng);
 template<class Engine>
 result_type operator()(Engine& eng,
 const param_type& par0);
private:
 result_type stored_a;
 result_type stored_b;
 };

Parameters
