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.
