std::experimental::ranges::UniformRandomNumberGenerator - cppreference.com (original) (raw)

The concept UniformRandomNumberGenerator<G> specifies that G is the type of a uniform random number generator, that is, objects of type G is a function object returning unsigned integer values such that each value in the range of possible results has (ideally) equal probability of being returned.

UniformRandomNumberGenerator<G> is satisfied only if, given any object g of type G:

• G::min() and G::max() are prvalue constant expressions;
• G::min() < G::max()
• g() is in the range [G::min(), G::max()]
• g() has amortized constant complexity.
