ChangeCalculator Program C++

changeCalc.cpp

#include <iostream>
#include <math.h>  
using namespace std;

int main() {
    //reads from input file, or takes user input. 1st is your total amount, and the second is how much you paid
    double total; 
    //get change
    cin >>total;
    
    double paid;
    cin >> paid;
    
    
    double change = paid - total;
    if(paid > total)
    {
    int quarters = change/.25;
    int dimes = (change - .25*quarters)/.10;
    int nickels = (change - .25*quarters - .10*dimes)/.05;
    int pennies = (change - .25*quarters - .10*dimes - .05*nickels)/.01;
    
    cout <<"Q: " << quarters << endl;
    cout <<"D: " << dimes <<endl;
    cout <<"N: " << nickels <<endl;
    cout <<"P: " << pennies << endl;
    
    }
    else
        cout << "You can't pay less than the total, now you owe money.";
    }
    
  
}

Program has a problem with input 0.03 total and 0.01 cost for instance.
