Which of the following statements should be used to obtain a remainder after dividing 3.14 by 2.1?

• rem = 3.14 % 2.1;
• rem = modf(3.14, 2.1);
• rem = fmod(3.14, 2.1);
• Remainder cannot be obtain in floating point division.

#include <stdio.h>
#include <math.h>

int main ()
{
  printf ("fmod of 3.14/2.1 is %lf\n", fmod (3.14,2.1) );
  return 0;
}
