std::geometric_distribution::geometric_distribution

STD：几何[医]分布：：几何[医]分布

explicit geometric_distribution( double p = 0.5 (1)(since C++11)
explicit geometric_distribution( const param_type& params (2)(since C++11)

构造新的分发对象。第一个版本使用p作为分发参数，第二个版本使用params作为分布参数。

参数

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

注记

要求0<p<1。
