OK, I'm more than partially confused.

I think my computer and/or processor is an x86 but I'm not sure.
My Windows 7 is 32-bit (can I have 64?)
My Csound is version 5.17 (double samples) and I assume that means 64-bit.

...How can I be running a 64-bit Csound if my OS is only 32?
does an x86 have 64-bit capability or 32 ONLY?

I'm using a laptop by Acer and it's an Aspire 5738-6252.
The SNID # somewhere on the back of the laptop is 00605129720.

to much information? please help the confused one.

The 64-bit has nothing to do with the OS. It merely shows the
precision of the audio samples Csound uses internally. The better the
precision the better the quality. In the past using the doubles
version of Csound in real time caused minor performance issues but
these days I don't think it's an issue.

Hi,

double samples means that csound uses 64-bit floating point number for its 
inner calculations, it is not bound to software architcture. So it can run 
perfectyl on 32bit systems.

In the case of precision not being bound to architecture, why not use
something like mpfr to get more precision?

Double precision floating point arithmetic is computed in the hardware
floating point unit part of the CPU, which is extremely efficient. I
would be quite surprised if MPFR were faster than the FPU. At any rate
it would require changing practically every line of Csound code.

Sorry. I just figured that since MPFR is used to build GCC that it
would be great for Csound.
