NAME

trand - return a random integer within a specified range

SYNOPSIS

value = trand([minimum,] maximum)

DESCRIPTION

Call trand to get a random integer 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 trand. 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 trand. If minimum is not present, trand will return an integer value between 0 and maximum.

RETURNS

A random integer between minimum (or 0) and maximum.

EXAMPLES

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

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