Help converting number to Hours/Minutes/Seconds

[Esanders323]

Hi,

I'm trying to create a program in C++ that generates a random number, like 173.5 and convert it to Hours/Minutes/Seconds. So it would take 173.5 and give me 2 Hours, 53 Minutes, and 30 seconds.

The beginning is my random number generator that helps the numbers be more random. I have that working fine. What I want to get to work is the other part.

#include <iostream>

using namespace std;

int main()

{
cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(1);
    srand(time(0));
    double rnd1, rnd2, rnd3, rnd4; 
    int hours, minutes;
    //This part works fine
    do
    {
    rnd1 = rand();
    rnd2 = (rand() % 10) + 1;
    rnd3 = (rnd1 / rnd2);
    } while(rnd3 > 14000);
    rnd4 = (rnd3 / 10);
    cout << rnd4 << endl;
    // ^ works fine
    
    //Need help here
    hours = (rnd4 / 60);
    minutes = (rnd4-(60*hours));
    
    cout << hours <<endl;
    cout << minutes <<endl;
    system("pause");
    
    
    return 0;
}

Thanks

Well I thought about it a bit more and think I got a bit closer.

#include <iostream>

using namespace std;

int main()

{
cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(1);
    srand(time(0));
    double rnd1, rnd2, rnd3, rnd4; 
    int hours, minutes, seconds;
    
    //This part works fine
    do
    {
    rnd1 = rand();
    rnd2 = (rand() % 10) + 1;
    rnd3 = (rnd1 / rnd2);
    } while(rnd3 > 14000);
    rnd4 = (rnd3 / 10);
    cout << rnd4 << endl;


    // ^ works fine
    
    //Need help here
    hours = (rnd4 / 60);
    minutes = (rnd4-(60*hours));
    seconds = (rnd4-((hours*60)+minutes))*60;
    cout << hours <<endl;
    cout << minutes <<endl;
       cout << seconds <<endl;
    system("pause");
    
    
    return 0;
}

The only problem is that sometimes the numbers are off by 1 or so.
For instance I just ran the program and the random number I received was 303.0. It then came up with 3 hours 22 minutes 58 seconds. It should be 3 hours 23 Minutes 0 seconds
I believe that has to do with rounding up/down.
Anything I can do to fix that?

Thanks
