UTIL_ExpRand

function

Library: Utilities (OMUTIL legacy)
Include: omutil.xin

Returns: random numbers based on the exponential distribution


Declaration 
define external integer function UTIL_ExpRand (value integer lambda)


Purpose

Use this function to generate random numbers based on the exponential distribution. Over a large number of trials, the average over all of the generated random numbers will tend towards the argument lambda.

Example:

This program generates 1000 random numbers with an exponential distribution and an average value of 20. 

  
  include "omutil.xin"
  
  process
       local integer lambda initial {20} ; average value
  
       repeat for integer i from 1 to 1000
          output "d" % i || ": "
              || "d" % UTIL_ExpRand(lambda) || "%n"
       again
