+ * - the member function @c next should change the state of the generator to the next generated value

+//! of the @c begin and @c end parameters.
+//! - The third overload generates numbers using the named parameter inside @c params , which are:
+//! - @c distribution: the distribution used. In this overload, since the type of the samples cannot be deduced,
+//! the samples are of type @c double and the distribution is uniform real in [0, 1).
+//! - @c seed: the seed for generating the values
+//! - @c engine: the random number generator engine
