Which of the following statement obtains the remainder on dividing 5.5 by 1.3 ?
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 5.5 by 1.3 is %lf\n", fmod (5.5, 1.3) );
return 0;
}
Output:
fmod of 5.5 by 1.3 is 0.300000

modf() function is used to calculate integer part and fractional part of a double or float value.
fmod() function is used to calculate modulo division for float and double values since % operator doesn't work for float and double values.

fmod() is the library function defined in math.h file.
To calculate remainder of floating point numbers.
Syntax : fmod(x,y);
To calculate remainder of floating point numbers.
Syntax : fmod(x,y);

What's the use of 'math.h' and why should we use?

According to me.
Rem = (x%y) ___is used to calculate remainder of integer numbers, but it is not applicable for float numbers.
So here we use.
Rem = fmod (x, y) ___where 'fmod' comes in 'math.h' library.
So here option (A) is wrong & option (C) is correct.
