geometric_distribution() : geometric_distribution(0.5) {}
(1)
(since C++11)
explicit geometric_distribution( double p );
(2)
(since C++11)
explicit geometric_distribution( const param_type& params );
(3)
(since C++11)
Constructs a new distribution object.
2) Uses p as the distribution parameter.
3) Uses params as the distribution parameter.
[edit] Parameters
p
-
the p distribution parameter (probability of a trial generating true)
params
-
the distribution parameter set
[edit] Notes
Requires that 0 < p < 1.
[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 |
|---|---|---|---|
| P0935R0 | C++11 | default constructor was explicit | made implicit |
