#include <stdio.h>
int main(void)
{
  double    a = 25834242042.0;
  float     b = 25834242042.0;    
  long long c = 25834242042;

  printf("   double: %.1f\n", a);
  printf("    float: %.1f\n", b);
  printf("long long: %Ld\n",  c);
  return 0;
}

Compile with djgpp and run...

   double: 25834242042.0
    float: 25834242048.0
long long: 25834242042

Notice the round-off error in the float.
