Hi Bill,

Are you asking about 64bit integer arithmetic?

With most compilers you can use "long long" for 64 bit arithmetic even
on 32bit platforms. 

This is at least true for GCC, Sun Workst^Hhop Pro and HP aCC. For
vendor compilers you may need to give the compiler switches to enable it
(e.g. on HP acc -Ae I think...).

Failing that, packages like GMP provide arbitrary precision support, but
that might be more that you really need.

Cheers,
Alex.
