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

That is right answer because the given expression is in the floating type formate so witought fmod() is use that not give right answer so fmod() is used.

What is use of fmod() function ?

Yes fmod is the correct ans as in for floating division.

What Swathy said would be the exact explanation.

Yes. For int only we can use mod for float we should use fmod the answer should be c only for this problem.

%(modulo) operator is in arithmatic
fmod is the c function
fmod is the c function

% operator represents Reminder in C Language
But it is not possible for floating point operations.So,the Answer would be option (d).
(d)Remainder cannot be obtain in floating point division.

The answer could be option A (i.e) rem = 3.14 % 2.1 ?
