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.
Answer: Option
Explanation:

fmod(x,y) - Calculates x modulo y, the remainder of x/y.
This function is the same as the modulus operator. But fmod() performs floating point divisions.

Example:


#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;
}

Output:
fmod of 3.14/2.1 is 1.040000

% operator is not use for floating operations it is only used for integers.

fmod() outdated and is not supported by gcc compilers hence answer is(D).

fmod(x,y) function is used to get remainder of floating point divisions.

For floating point operator % cannot be used. Only operator/can be used.

What does the fmod represent here?

How could the answer be c but not a?

Why array's base address is initialized to 0 and it terminates on -1?
Ayesha said:   2 years ago
Option D is right because the floating point is not applicable for %.
