Extracts a binomial_distribution random number distribution __x from the input stream __is.

Detailed Description

template<typename _IntType = int>

class std::binomial_distribution< _IntType >" A discrete binomial random number distribution.

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.
