    I'm working with decimal number, and this is my code:

    double fraction = 3/4;
    qDebug() << fraction
    

    Instead of 0.75, QtCreator display 0. Is a QtCreator bug, or my procedure is wrong? If so, you could tell me which is the right one?

    Thanks in advance

        You are dividing two integers. Integer-Division of a value by a larger value results to zero by definition in C++. As long as you are not making one value a double there will be no implicit cast in C++ before assigning the result to the double.
