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. (2) uses mean as the distribution parameter. (3) uses params as the distribution parameter.

Parameters

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

Notes

Requires that 0 < mean.
