const param_type &__p)
double p () const
Returns the p parameter of the distribution. param_type
param () const
Returns the parameter set of the distribution. void param (const
param_type &__param)
Sets the parameter set of the distribution. void reset ()

Friends¶
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.
