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
