Thread: implicit casting?

I'm doing an exercise which needs to find a percentage of something...
In the code below, when I initialise x with 100.0 / 8.0 it the output is correct, however. If I write x = 100 / 8 it says 10.64. I know its something to do with the values written as integers but what is the computer actually doing here?

Many thanks

Code:

int main()
{
    
    //double input;
    double price = 128.0;
    double x;
    
        x = 100.0 / 8.0;


        price/= x;
        
        cout << "Price with 8% discount: " <<  price << endl;


    return 0;
}

Pretty sure a proper discount would be price *= (1.0 - x); 10.64 ought to be the amount you save, and not the final price.
