Description

MODULE randomNumber_mod (prefix=’rng’ category=’8. Low-level utilities and constants’)

Purpose

A Gaussian random number generator (RNG) module. The actual calculation is performed by functions in an external library.

Quick access

Routines

rng_gaussian(), rng_setup(), rng_uniform()

Needed modules

• iso_c_binding

Variables

Subroutines and functions

subroutine  randomnumber_mod/rng_setup(seed)

Purpose

Initialize the random number generator with a supplied seed.

Arguments

seed [integer ,in]
