Produces a random boolean value with probability p of being true.

Synopsis

Declared in <absl/random/distributions.h>

template<typename URBG>
bool
Bernoulli(
    URBG&& urbg,
    double p);

Description

absl::Bernoulli produces a random boolean value, with probability p (where 0.0 <= p <= 1.0) equaling true.

Prefer absl::Bernoulli to produce boolean values over other alternatives such as comparing an absl::Uniform() value to a specific output.

See https://en.wikipedia.org/wiki/Bernoulli_distribution

Example:

absl::BitGen bitgen; ... if (absl::Bernoulli(bitgen, 1.0/3721.0)) { std::cout << "Asteroid field navigation successful."; }

Return Value

A random boolean value.

Parameters

Name

Description

urbg

The uniform random bit generator.

p

The probability (in [0, 1]) of producing true.
