I have a few questions about the use of _INTEGER64 and _UNSIGNED _INTEGER64.
According to the WIKI info, _UNSIGNED _INTEGER64 values can range from 0 to 18446744073709551615 on 64 bit computers and the 32 bit values are limited to the _INTEGER64 values of -9223372036854775808 to 9223372036854775807.
However, the WIKI page for _UNSIGNED doesn't mention any difference between 32 bit or 64 bit use.
Question :
Has the problem of not being able to use the higher values still apply to 32 bit systems?
The reason I ask is that I am currently running QB64pe 32bit on a Windows Vista Home Premium 32 bit Operating System and I'm able to get the higher values for an _UNSIGNED _INTEGER64 to work without any problems.
PLEASE NOTE : This all runs on a computer that IS CAPABLE of running a 64 bit OS installation.
>> Processor : AMD Athlon(tm) 64X2 Dual Core Processor 5000+ 2.60 Ghz
More questions:
So, does this mean that ONLY the computer needs to be capable of 64 bit?
When QB64 does _UNSIGNED _INTEGER64 math, does it use the processor's internal math co-processor?
If I were using QB64pe 32 bit on a 32 bit Operating System which was running on a 32 bit processor (not capable of running a 64 bit OS) would I still be able to get the higher values for an _UNSIGNED _INTEGER64 variable?
Thanks in advance for any more detailed info that can be provided.
