< cpp | numeric | random | exponential distribution
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.
Parameters
lambda | - | the λ distribution parameter (the rate parameter) |
params | - | the distribution parameter set |
Notes
Requires that 0 < lambda.
