## Class template geometric_distribution

boost::geometric_distribution

## Synopsis

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

    template<typename IntType = int, typename RealType = double>
    class geometric_distribution {
    public:
      // types
      typedef RealType input_type;
      typedef IntType  result_type;

      // construct/copy/destruct
      geometric_distribution(const RealType & = RealType(0.5));

      // public member functions
      RealType p() const;
      void reset() ;
      template<typename Engine> result_type operator()(Engine &) ;
    };

## Description

An instantiation of the class template `geometric_distribution` models a random distribution . The distribution produces positive integers which are the number of bernoulli trials with probability `p` required to get one that fails.

For the geometric distribution, .

### `geometric_distribution` public construct/copy/destruct

1.     geometric_distribution(const RealType & p = RealType(0.5));

   Contructs a new geometric_distribution with the paramter `p`.

   Requires: 0 < p < 1

### `geometric_distribution` public member functions

1.     RealType p() const;

   Returns: the distribution parameter `p`

2.     void reset() ;

3.     template<typename Engine> result_type operator()(Engine & eng) ;
