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.
subroutine pmc_rand::pmc_rand_finalize ()
 Cleanup the random number generator.
real(kind=dp) pmc_rand::pmc_random ()
 Returns a random number between 0 and 1.
integer pmc_rand::pmc_rand_int (n)
 Returns a random integer between 1 and n.
integer 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.
integer pmc_rand::rand_poisson (mean)
 Generate a Poisson-distributed random number with the given mean.
integer pmc_rand::rand_binomial (n, p)
 Generate a Binomial-distributed random number with the given parameters.
real(kind=dp) pmc_rand::rand_normal (mean, stddev)
 Generates a normally distributed random number with the given mean and standard deviation.
integer pmc_rand::sample_cts_pdf (pdf)
 Sample the given continuous probability density function.
integer pmc_rand::sample_disc_pdf (pdf)
 Sample the given discrete probability density function.
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.
character pmc_rand::rand_hex_char ()
 Generate a random hexadecimal character.
subroutine pmc_rand::uuid4_str (uuid)
 Generate a version 4 UUID as a string.

Variables

integer, parameter pmc_rand::PMC_UUID_LEN = 36
 Length of a UUID string.
integer, parameter pmc_rand::PMC_RAND_GSL_SUCCESS = 0
 Result code indicating successful completion.
integer, parameter pmc_rand::PMC_RAND_GSL_INIT_FAIL = 1
 Result code indicating initialization failure.
integer, parameter pmc_rand::PMC_RAND_GSL_NOT_INIT = 2
 Result code indicating the generator was not initialized when it should have been.
integer, parameter pmc_rand::PMC_RAND_GSL_ALREADY_INIT = 3
 Result code indicating the generator was already initialized when an initialization was attempted.
