binomial_distribution() : binomial_distribution(1) {}
(1) (since C++11)
explicit binomial_distribution( IntType t, double p = 0.5 );
(2) (since C++11)
explicit binomial_distribution( const param_type& params );
(3) (since C++11)

Constructs a new distribution object. (2) uses t and p as the distribution parameters. (3) uses params as the distribution parameters.

Parameters

t - the t distribution parameter (number of trials)
p - the p distribution parameter (probability of a trial generating true)
params - the distribution parameter set

Notes

Requires that 0 ≤ p ≤ 1 and 0 ≤ t.
