NAME

irand - return a random number within a specified range

SYNOPSIS

value = irand(minimum, maximum)

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, maximum

These mandatory arguments define the range within which falls the random value returned by irand.

RETURNS

A random number between minimum and maximum, inclusive.

EXAMPLES

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

prints 20 random numbers having values between -30 and 10, inclusive.
