    Hello DP Forum People, I have this problem of getting the decimal of a number? How can I get it and copy to a variable?

    ex.... 1234.59

    I used a for loop in order to get the index value of 59, my problem was with the value? how can I transfer this index number to a variable?

    Use modf. (This is to someone who's looking for the same thing)

    
//Example will output decimal and integer parts of 12.34
#include <cmath>
#include <iostream>

using namespace std;

int main()
{
    double x;
    modf(12.34, &x);  
    cout<<"Decimal: "<<modf(12.34, &x)<<"Fractional: "<<x;
}
    Code (markup):
