## Class template bernoulli_distribution

boost::compute::bernoulli_distribution — Produces random boolean values according to the following discrete probability function with parameter p : P(true/p) = p and P(false/p) = (1 - p)

## Synopsis

    // In header: <boost/compute/random/bernoulli_distribution.hpp>

    template<typename RealType = float>
    class bernoulli_distribution {
    public:

      // public member functions
      bernoulli_distribution(RealType = 0.5f);
      ~bernoulli_distribution();
      RealType p() const;
      template<typename OutputIterator, typename Generator>
        void generate(OutputIterator, OutputIterator, Generator &,
                      command_queue &);

      // private member functions
       BOOST_STATIC_ASSERT_MSG(boost::is_floating_point< RealType >::value,
                               "Template argument must be a floating point type");
    };

## Description

The following example shows how to setup a bernoulli distribution to produce random boolean values with parameter p = 0.25

### `bernoulli_distribution` public member functions

1.     bernoulli_distribution(RealType p = 0.5f);

   Creates a new bernoulli distribution.

2.     ~bernoulli_distribution();

   Destroys the bernoulli_distribution object.

3.     RealType p() const;

   Returns the value of the parameter p.

4.     template<typename OutputIterator, typename Generator>
         void generate(OutputIterator first, OutputIterator last,
                       Generator & generator, command_queue & queue);

   Generates bernoulli distributed booleans and stores them in the range [`first`, `last`).

### `bernoulli_distribution` private member functions

1.      BOOST_STATIC_ASSERT_MSG(boost::is_floating_point< RealType >::value,
                                "Template argument must be a floating point type");
