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

What is the use of return 0 there?

#include <stdio.h>
#include <math.h>
int main ()
{
int rem;
rem=3.14/2.1;
printf ("rem= %d\n", rem);
return 0;
}
0p:1.
#include <math.h>
int main ()
{
int rem;
rem=3.14/2.1;
printf ("rem= %d\n", rem);
return 0;
}
0p:1.

What is the difference between modf and fmod?

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.

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

% 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.

fmod() outdated and is not supported by gcc compilers hence answer is(D).
