std::geometric_distribution (3) - Linux Manuals
std::geometric_distribution - std::geometric_distribution
Defined in header <random>
template< class IntType = int > (since C++11)
Produces random non-negative integer values i, distributed according to discrete probability function:
The value represents the number of yes/no trials (each succeeding with probability p) which are necessary to obtain a single success.
std::geometric_distribution<>(p) is exactly equivalent to std::negative_binomial_distribution<>(1, p). It is also the discrete counterpart of std::exponential_distribution.
std::geometric_distribution satisfies RandomNumberDistribution
IntType - The result type generated by the generator. The effect is undefined if this is not one of short, int, long, long long, unsigned short, unsigned int, unsigned long, or unsigned long long.
