Thread: Good Random Number Generator

Hi,

Im using the Monte Carlo method to get an estimate of Pi.

I generate numbers between 0.0 and 1.0, using the following function (similar to the one in the FAQ)

Code:

double generate_rand(double min, double max)
{

  static int Init = 0;
  double rc;
  
  if (Init == 0)
  {
    srand(time(NULL));
    Init = 1;
  }
   rc =  (rand() / (RAND_MAX + 1.0) * (max - min) + min);
   return rc;
}

The estimation of pi depends on the quality of the random number generator, I was wondering if there is any way to make my function generate 'better' random numbers?
