Description
The vRngBernoulli function generates Bernoulli distributed random numbers with probability p of a single trial success, where
p∈R; 0 ≤ p ≤ 1.
A variate is called Bernoulli distributed, if after a trial it is equal to 1 with probability of success p, and to 0 with probability 1 - p.
The probability distribution is given by:
P(X = 1) = p
P(X = 0) = 1 - p
The cumulative distribution function is as follows:

Return Values
- VSL_ERROR_OK, VSL_STATUS_OK
Indicates no error, execution is successful.
- VSL_ERROR_NULL_PTR
stream is a NULL pointer.
- VSL_RNG_ERROR_BAD_STREAM
stream is not a valid random stream.
- VSL_RNG_ERROR_BAD_UPDATE
Callback function for an abstract BRNG returns an invalid number of updated entries in a buffer, that is, < 0 or > nmax.
- VSL_RNG_ERROR_NO_NUMBERS
Callback function for an abstract BRNG returns 0 as the number of updated entries in a buffer.
- VSL_RNG_ERROR_QRNG_PERIOD_ELAPSED
Period of the generator has been exceeded.
- VSL_RNG_ERROR_ARS5_NOT_SUPPORTED
ARS-5 random number generator is not supported on the CPU running the application.
