NAME¶

std::exponential_distribution::exponential_distribution - std::exponential_distribution::exponential_distribution

Synopsis¶

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.
