      poisson_distribution(): poisson_distribution(1.0){}
      (1)(since C++11)
      explicit poisson_distribution(double mean);
      (2)(since C++11)
      explicit poisson_distribution(const param_type& params);
      (3)(since C++11)

      Constructs a new distribution object.

      1) Uses1.0 as the distribution parameter.
      2) Usesmean as the distribution parameter.
      3) Usesparams as the distribution parameter.

      [edit]Parameters

      mean - theμ distribution parameter (the mean of the distribution)
      params - the distribution parameter set

      [edit]Notes

      Requires that0< mean.
