Modules
module	pmc_rand
	Random number generators.

Functions/Subroutines
subroutine	pmc_rand::pmc_srand (seed, offset)
	Initializes the random number generator to the state defined by the given seed plus offset. If the seed is 0 then a seed is auto-generated from the current time plus offset. More...
subroutine	pmc_rand::pmc_rand_finalize ()
	Cleanup the random number generator. More...
real(kind=dp) function	pmc_rand::pmc_random ()
	Returns a random number between 0 and 1. More...
integer function	pmc_rand::pmc_rand_int (n)
	Returns a random integer between 1 and n. More...
integer function	pmc_rand::prob_round (val)
	Round val to floor(val) or ceiling(val) with probability proportional to the relative distance from val. That is, Prob(prob_round(val) == floor(val)) = ceil(val) - val. More...
integer function	pmc_rand::rand_poisson (mean)
	Generate a Poisson-distributed random number with the given mean. More...
integer function	pmc_rand::rand_binomial (n, p)
	Generate a Binomial-distributed random number with the given parameters. More...
real(kind=dp) function	pmc_rand::rand_normal (mean, stddev, prob_threshold)
	Generates a normally distributed random number with the given mean and standard deviation. More...
subroutine	pmc_rand::rand_normal_array_1d (mean, stddev, val)
	Generates a vector of normally distributed random numbers with the given means and standard deviations. This is a set of normally distributed scalars, not a normally distributed vector. More...
subroutine	pmc_rand::sample_without_replacement (sample_size, population_size, sample)
	Generates a vector of indices for a sample set from a population without replacement. More...
integer function	pmc_rand::sample_cts_pdf (pdf)
	Sample the given continuous probability density function. More...
integer function	pmc_rand::sample_disc_pdf (pdf)
	Sample the given discrete probability density function. More...
subroutine	pmc_rand::sample_vec_cts_to_disc (vec_cts, n_samp, vec_disc)
	Convert a real-valued vector into an integer-valued vector by sampling. More...
character function	pmc_rand::rand_hex_char ()
	Generate a random hexadecimal character. More...
subroutine	pmc_rand::uuid4_str (uuid)
	Generate a version 4 UUID as a string. More...

Variables
integer, parameter	pmc_rand::pmc_uuid_len = 36
	Length of a UUID string. More...
integer, parameter	pmc_rand::pmc_rand_gsl_success = 0
	Result code indicating successful completion. More...
integer, parameter	pmc_rand::pmc_rand_gsl_init_fail = 1
	Result code indicating initialization failure. More...
integer, parameter	pmc_rand::pmc_rand_gsl_not_init = 2
	Result code indicating the generator was not initialized when it should have been. More...
integer, parameter	pmc_rand::pmc_rand_gsl_already_init = 3
	Result code indicating the generator was already initialized when an initialization was attempted. More...
