then tested with qmake message($$QT_VERSION) got 6.0.0
than

template<int A> class Check
{
public:
    static_assert (QT_VERSION < 0x060100, "fff");

    static constexpr bool value = A >= 0x060100;
};

constexpr bool c = Check<QT_VERSION>::value;

got

393473 is 0x060101 .... 0.o

then

template<int a, int b,int c> class Check
{
public:
    static_assert (QT_VERSION_MAJOR == 0x06, "sss");
    static_assert (QT_VERSION_MINOR == 0x00, "ddd");

    static constexpr bool value = a >= 0x060100;
};

constexpr bool c = Check<QT_VERSION_MAJOR, QT_VERSION_MINOR, QT_VERSION_PATCH>::value;

got

math is making magic?
'Check<a,b,c>' this way is not showing nombers any more at all...
what is wrong?
