float bnldev	(	float	pp,
		int	n,
		long *	idum
	)

Name: bnldev

Synopsis: float bnldev(float pp, int n, long *idum);

Version: 1.0

Description: returns as a floating point number an integer value that is a random deviate drawn from a binomial distribution of n trials each of probability pp

Inputs: 1- the probability of a trial 2 - the numbe of trials 3 - a pointer to a long (if the long is negative the random number generator is reinitialized)

Return: a randonm number with the above distribution

See Also: expdev

double expdev ( long * idum)

Name: expdev

Synopsis: double expdev(long *idum);

Version: 1.0

Description: produces a random number with gaussian distribution

Authors & Date: Riccardo Rigon, 1998

Inputs: a pointer to a long (if the long is negative the random number generator is reinitialized)

Return: a random number with gaussian distribution (zero mean and standard deviation 1)

float gammln ( float xx)

Name: gammln

Synopsis: float gammln(float x);

Version: 1.0

Description: returns the value of log(gamma(x))

Inputs: 1- the abscissa for which you need the value of the gamma

Return: a randonm number with the above distribution

double poisdev	(	float	xm,
		long *	idum
	)

Name: poisdev

Synopsis: double poisdev(float xm, long *idum);

Version: 1.0

Description: Generates a random number with poisson distribution

Inputs: 1- the distribution mean 2 - a pointer to a long (if the long is negative the random number generator is reinitialized)

Return: a randonm number with poisson distribution
