irand - return a random number within a specified range


Synopsis

value = irand([minimum,] maximum)

Parameters inside the [brackets] are optional.


Description

Call irand to get a random number that falls within the range specified by the arguments.

It's a good idea to call srand once to seed the random number generator before using irand. Otherwise, a seed of 1 will be used.


Arguments

minimum [optional], maximum
These arguments define the range within which falls the random value returned by irand. If minimum is not present, irand will return a value between 0.0 and maximum. The bounds are inclusive.


Examples

   srand(0)
   min = -30
   max = 10
   for (i = 0; i < 20; i = i + 1) {
      randval = irand(min, max)
      print(randval)
   }
