Detailed Description

Generate random numbers. The standard rand() function returns random integers in the range [0, RAND_MAX]. The goal is to obtain uniformly-distributed numbers in the range [low, high]. To achieve properly distributed numbers, check whether the value rand() returns is in the range [0, (high-low+1)*k] where k is the largest integer such that (high-low+1)*k < RAND_MAX. If the random number is out of range, discard it and get another one. Then take the value mod (high-low+1) and add low to get the random result.

Constructor & Destructor Documentation

randomint::randomint	(	int	low,
		int	high
	)			[inline]

Construct a random-number generator to produce numbers in the range [low, high]. If low > high the values are reversed. This class uses the std::rand() function, so you call std::srand() to change the seed.
