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

% 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.

Hai friends, mod() is used for the integer division to get remainder. Where as fmod() is used to get floating point remainder. We find both mod() and fmod()in math.h header file check it once.

printf ("fmod of 3.14/2.1 is %d\n", fmod(3,2) );
return 0;
}
I am getting output as 0. Anyone can explain it why?

% in c language represents remainder after division,
The number can be of integer or float but in global declaration reminder should be declared in float irrespective of declared variables.

modf(x, y) is used to split the float point in to the intpart and factpart.
Ex: 3.13=3.00+0.13
fmod(x,y) is used to find the remainder in floating points.
Ex: fmod(3.14,2.1)
Ex: 3.13=3.00+0.13
fmod(x,y) is used to find the remainder in floating points.
Ex: fmod(3.14,2.1)

float i,j;
i=3.14;j=2.1;

Usually % (modules) operator not for floating point numbers, so in c fmod is inbuilt function that will use to get the reminder of the floating point number. Answer is C.
