std::extreme_value_distribution
Defined in header <random> | ||
|---|---|---|
template< class RealType = double > class extreme_value_distribution; | (since C++11) |
Produces random numbers according to the extreme value distribution (it is also known as Gumbel Type I, log-Weibull, Fisher-Tippett Type I): p(x;a,b) =
| 1 |
| b |

std::extreme_value_distribution satisfies all requirements of RandomNumberDistribution.
Template parameters
| RealType | - | The result type generated by the generator. The effect is undefined if this is not one of float, double, or long double. |
Member types
| Member type | Definition |
|---|---|
result_type | RealType |
param_type | the type of the parameter set, see RandomNumberDistribution. |
Member functions
| constructs new distribution (public member function) |
|
| resets the internal state of the distribution (public member function) |
|
Generation |
|
| generates the next random number in the distribution (public member function) |
|
Characteristics |
|
| returns the distribution parameters (public member function) |
|
| gets or sets the distribution parameter object (public member function) |
|
| returns the minimum potentially generated value (public member function) |
|
| returns the maximum potentially generated value (public member function) |
|
Non-member functions
| compares two distribution objects (function) |
|
| performs stream input and output on pseudo-random number distribution (function template) |
