Detailed Description
template<typename _IntType = int>class std::binomial_distribution< _IntType >n A discrete binomial random number distribution. o m The formula for the binomial probability density function is $p(i|t,p) = {} p^i (1 - p)^{t - i}$ where $t$ and $p$ are the parameters of the distribution. n } Definition at line 3400 of file random.h. {
Member Typedef Documentation
template<typename _IntType = int> typedef _IntType std::binomial_distribution< _IntType >::result_type The type of the range of the distribution. Definition at line 3403 of file random.h.
Member Function Documentation
template<typename _IntType = int> result_type std::binomial_distribution< _IntType >::max () const [inline] Returns the least upper bound value of the distribution. Definition at line 3510 of file random.h. template<typename _IntType = int> result_type std::binomial_distribution< _IntType >::min () const [inline] Returns the greatest lower bound value of the distribution.
