+---DRnd
The DRnd class implements a pseudo random generator bases on a linair congruential generator. This is the most commonly used type, it is fast but it has some well-known flaws. See class DMRnd and class DLRnd for a better, but slower pseudo random generator.
#include <stdio.h>
#include "ofc/DRnd.h"
int main(int argc, char *argv[])
{
DRnd *rnd1 = [DRnd alloc];
DRnd *rnd2 = [DRnd new ];
[rnd1 init :12345678]; // Init with a seed value
// Get pseudo random values
printf("Pseudo random long value:%ld.\n", [rnd1 nextLong]);
printf("Pseudo random int value with range [1,100]:%d.\n", [rnd1 nextInt :1 :100]);
[rnd2 seed :87654321]; // Set a seed value
// Get pseudo random values
printf("Pseudo random double value:%f.\n", [rnd2 nextDouble]);
printf("Pseudo random double value with range [0.1,0.3]:%f.\n", [rnd2 nextDouble :0.1 :0.3]);
[rnd1 free]; // Cleanup
[rnd2 free];
return 0;
