Visual Studio has supported 64-bit int types (long long) since at least Visual Studio 2005. See

_MSC_VER evaluates to the version of the Visual Studio compiler. See here:

I see a lot of sal_uInt64 in the code. Is that supported for
Windows? As far as I know at least the MSVC Express has only 4Byte

Umm.. now that you mention.. sal/inc/sal/types.h has

#if (_MSC_VER >= 1000)
    typedef __int64                  sal_Int64;
    typedef unsigned __int64         sal_uInt64;

so what evaluates _MSC_VER to in MSVCE?

Also noticing there

    #define SAL_CONST_UINT64(x)      x##ui64

so the constant I introduced probably should use that.

If MSVCE doesn't support 64bit values I might do some tricks using the
double mantissa.
