Collaboration diagram for Continuous Distributions:

Uniform discrete distribution for random numbers. A discrete random distribution on the range $[min, max]$ with equal probability throughout the range.

The type of the parameters of the distribution.

The type of the range of the distribution.

Constructs a uniform distribution object.

Gets the inclusive lower bound of the distribution range.

Gets the inclusive upper bound of the distribution range.

Resets the distribution state.

Does nothing for the uniform integer distribution.

Gets a uniformly distributed random number in the range $(min, max)$.

Gets a uniform random number in the range $[0, n)$.

This function is aimed at use with std::random_shuffle.

Inserts a uniform_int random number distribution __x into the output stream os.

Parameters
__osAn output stream.
__xA uniform_int random number distribution.
Returns
The output stream with the state of __x inserted or in an error state.

Extracts a uniform_int random number distribution __x from the input stream __is.

Parameters
__isAn input stream.
__xA uniform_int random number generator engine.
Returns
The input stream with __x extracted or in an error state.

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.
