Thread: random generators

RAND_MAX works like a charm
however i was trying to write the function using drand48 and erans48, can you tell me what am i doing wrong

Code:

#include <stdio.h>
#include <time.h>
int main(void)
{
  int number;
  float random_factor;
  float random_number;
  random_number=0;
  printf("What is the number?");
  scanf("%d",&number);
  drand48( (unsigned int)time(NULL));
  random_factor=erand48();
  random_number=random_factor*(float)number;
  printf("\n Number is %d",number);
  printf("\nRandom Factor is %f",random_factor);
  printf("\nRandom Number is %f",random_number);
  return 0;
 
}

but i get the following results
What is the number?10

Number is 10
Random Factor is 0.000000
Random Number is 0.000000[
