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.
[edit] Parameters
lambda
-
the λ distribution parameter (the rate parameter)
params
-
the distribution parameter set
[edit] Notes
Requires that 0 < lambda.
[edit] Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
