Functions
void	seed (unsigned int seed)
	Sets the given seed for the random number generator.
template<typename T >
std::enable_if< std::is_integral< T >::value, T >::type	random (T min, T max)
	Returns a random number of given type on the range [min, max].

	Returns a random number of given type on the range [min, max].

Detailed Description

Global random number generator wrapping the std::random utilities.

Attention

Since random works using static variables, each translation unit will have its own 'random' state

Note

The first seed used before calling 'seed()' is random
