explicit exponential_distribution( RealType lambda = 1.0 ); | (1) | (since C++11) |
explicit exponential_distribution( const param_type& params ); | (2) | (since C++11) |
Constructs a new distribution object. The first version uses lambda as the distribution parameter, the second version uses params as the distribution parameter.
| lambda | - | the λ distribution parameter (the rate parameter) |
| params | - | the distribution parameter set |
Requires that 0 < lambda.
