32 vs 64 bit math

That has to be emulated support because ARM says there is no hardware support for it - https://developer.arm.com/documentation/ka004751/1-0

If the underlying C++ compiler / RTL supports 128-bit long double, then QB64-PE will support it as well.

I have a general question on the math capabilities available.  I am tied down rright now to a 32-bit Win 11 machine.  I would like to do some math operations using 64-bit integers.  Will QB 64 be able to give me the full precision of the 64-bits?  I realize that I will lose speed on the thunking from 32 to 64 bits, but I can always recompile and run on a 64-bit machine when I get access to one.

I want to start coding again since I have some forced free time so expect some more general under-the-hood type questions.

How are you running Windows 11 32-bit? As far as I know, Microsoft never released a 32-bit edition of Windows 11. Windows 10 was the last version to include one. Just curious.  Smile
