bool operator== (const bernoulli_distribution &__d1, const bernoulli_distribution &__d2)
Return true if two Bernoulli distributions have the same parameters.

Detailed Description

A Bernoulli random number distribution.

Generates a sequence of true and false values with likelihood $p$ that true will come up and $(1 - p)$ that false will appear.
