random.exponential

function

Library: Random number utilities (OMRANDOM)
Import : omrandom.xmd

Returns: Random numbers based on the exponential distribution.


Declaration 
define external integer function 
   exponential average value integer lambda


Purpose

Use random.exponential 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. 

  import "omrandom.xmd" prefixed by random.
  
  process
     repeat for integer i to 1000
        output "d" % i || ": "
            || "d" % random.exponential average 20
            || "%n"
     again
