Concept Framework 2.2 documentation

standard.C.math.srand

Name	Version	Deprecated
srand	version 1.0	no

Prototype:

number srand(number seed)

Parameters:

seed

[in] Seed for random-number generation

Description:

The srand function sets the starting point for generating a series of pseudorandom integers. To reinitialize the generator, use 1 as the seed argument. Any other value for seed sets the generator to a random starting point.

rand retrieves the pseudorandom numbers that are generated. Calling rand before any call to srand generates the same sequence as calling srand with seed passed as 1.

Example:

import standard.C.math
import standard.C.time

class Main {
     function Main() {
          /* Seed the random-number generator with current time so that
          * the numbers will be different every time we run.
          */
          srand(time());

          /* Display 10 numbers. */
          for(var i = 0; i < 10; i++)
               echo "" + rand() + "\n";
     }
}
