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

Function written inside block is called local function & used only within that block. Function declared before main program starts below the header files is called global function.
Scope of local function is only within that part of the program it can not be access in other function.

fmod() function or keyword is find used to find out.

#include<stdio.h>
main()
{
float a=3.14,b=2.1,c;
c=a%b;
pf("%d",c);
output: invalid operand to binary%
BUT
int a;
a=3.14%2.1;
pf("%d",a);
Output 1:
I think so, comma act as a operator. Please clear explanation.

What is REM?
And I also need some information about what is the difference between.
Rem = 3.14% 2.1; and rem = fmod (3.14, 2.1);

If you use % for fining remainder it will give you an integer value.
But the fmmod() function gives you remainder in floating point value.

Nice explanation but I am not clear about increment.
