class rng : public rcppsw::patterns::pimpl::pimpl<detail::rng_impl>

Random number generator class using the PIMPL pattern in order to not have to include <random>.

Public Functions

explicit rng(size_t seed)

~rng(void) override

bool bernoulli(double p): Return a selection according to a Bernoulli distribution with parameter p.

double exponential(double lambda): Return a selection according to the exponential distribution \(1 - e ^(-lambda)\).

double gaussian(double mean, double std_dev): Return a selection according to the Gaussian distribution \(G(\mu, \sigma)\).

inline size_t seed(void) const: Get the current seed.

template<typename T> inline T uniform(const range<T> &c_range): Return a uniform selection in the range specified by c_range.

template<typename T> T uniform(const T &lb, const T &ub): Return a uniform selection in the range [lb, ub].
