Detailed Description
A Bernoulli random number distribution.
Generates a sequence of true and false values with likelihood $p$ that
true will come up and $(1 - p)$ that false will appear.
Member Typedef Documentation
typedef bool std::bernoulli_distribution::result_type
The type of the range of the distribution.
