exponential_distribution() : exponential_distribution(1.0) {}	(1)	(since C++11)
explicit exponential_distribution( RealType lambda );	(2)	(since C++11)
explicit exponential_distribution( const param_type& params );	(3)	(since C++11)

Constructs a new distribution object. (2) uses lambda as the distribution parameter. (3) uses params as the distribution parameter.

Parameters

lambda	-	the λ distribution parameter (the rate parameter)
params	-	the distribution parameter set

Notes

Requires that 0 < lambda.
