I Have used define for Quarters . Quarters = .25. The line that is an error is change = coins % Quarters

Question

I can't seem to get modf to work. Can someone help? It might be called fmod.

    change = coins % Quarters; 

    if  (change >= Quarters)  
    { 
        change  = coins - Quarters; 
        printf ("%f", change  );
    }
        else 
    {
        printf ("%f", change);
    }

Answer 1

I decided to just make both variables multiplied by 100
