C++ Math fmod
The function finds the floating point remainder of numerator/denominator and rounded towards zero.
Formula of fmod:
Example
fmod= numerator - t*denominator
where 't' is the truncated value of numerator/denominator.
Syntax
Consider a numerator 'n' and denominator 'd'. Syntax would be:
Example
double fmod(double n,double d);
Parameter
n :The value of numerator.
d :The value of denominator
Return value
It returns the floating point remainder of n/d.
Note: If the value of denominator is zero, then fmod function will return NAN(Not a Number).
Example 1
Let's see a simple example of having same types of arguments.
Example
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
double n=4.2;
double d=7.8;
std::cout << "The values of numerator and denominator are :" <<n<<" , "<< d<< std::endl;
std::cout << "fmod of these values is :"<<fmod(n,d) <<std::endl;
return 0;
}
Output:
Output
The values of numerator and denominator are :4.2 , 7.8
fmod of these values is :4.2
Example 2
Let's see the simple example of having different types of arguments.
Example
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
float n=7.8;
int d=9;
std::cout << "The values of numerator and denominator are :" <<n<<" , "<< d<< std::endl;
std::cout << "fmod of these values is :"<<fmod(n,d) <<std::endl;
return 0;
}
Output:
Output
The values of numerator and denominator are :7.8 , 9
fmod of these values is :7.8
Example 3
Let's see the simple example when the value of denominator is zero.
Example
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
float n=16.7;
int d=0;
std::cout << "The values of numerator and denominator are :" <<n<<" , "<< d<< std::endl;
std::cout << "fmod of these values is :"<<fmod(n,d) <<std::endl;
return 0;
}
Output:
Output
The values of numerator and denominator are :16.7 , 0
fmod of these values is :-nan
