normal_distribution Class
Generates a normal distribution.
template<class RealType = double>
class normal_distribution {
public:
typedef T1 input_type;
typedef RealType result_type;
struct param_type;
explicit normal_distribution(result_type mean0 = result_type(0.0),
result_type sigma0 = result_type(1.0));

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_mean; // exposition only
result_type stored_sigma; // exposition only

Parameters
- RealType
The floating-point distribution value type.
Remarks
The template class describes a distribution that produces values of a user-specified floating-point type with a normal distribution.
