I need maximum number of quint64 for example we have a macro for ulong ULONG_MAX

Is there any equal macro for quint64?

Answer 1

You can find an answer in the official documentation:

quint64 is a typedef for unsigned long long int (unsigned __int64 on Windows). This type is guaranteed to be 64-bit on all platforms supported by Qt.

So, quint64 is a 64-bit type for unsigned integers. We can find its maximum value this way:

2^64-1 = 18446744073709551615

As it was told here, you can get the same result by including #include <limits>, and the output result of

std::numeric_limits<quint64>::max();
