Question

Which of the following statement obtains the remainder on dividing 5.5 by 1.3 ?


Options:
A .  rem = (5.5 % 1.3)
B .  rem = modf(5.5, 1.3)
C .  rem = fmod(5.5, 1.3)
D .  Error: we can't divide
Answer: Option C


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
