std::binomial_distribution<IntType>::param

From cppreference.com
 
 
Numerics library
 
Pseudo-random number generation
 
 
param_type param() const;
(1) (since C++11)
void param( const param_type& params );
(2) (since C++11)

Manages the associated distribution parameter set.

1) Returns the associated parameter set.
2) Sets the associated parameter set to params.

[edit] Parameters

params - new contents of the associated parameter set

[edit] Return value

1) The associated parameter set.
2) (none)

[edit] Complexity

Constant.

[edit] Example

Run this code
#include <iostream>
#include <random>
 
int main()
{
 std::random_device rd;
 std::mt19937 gen(rd());
 using BinomialDist = std::binomial_distribution <>;
 BinomialDist bino_dis(1, 0.5);
 
 std::cout << "A sample of Binomial( 1, 0.5): " << bino_dis(gen) << '\n';
 
 // Use another parameter set
 bino_dis.param(BinomialDist::param_type(100,0.9));
 std::cout << "A sample of Binomial(100, 0.9): " << bino_dis(gen) << '\n';
}

Possible output:

A sample of Binomial( 1, 0.5): 0
A sample of Binomial(100, 0.9): 94
