I the build-in int type has limited representation range. I'm wondering
if there is any class which can represent arbitrarily long integer like
what Mathematica does?

Thanks,
Peng

Did you try google? I'm convinced that there is an abundance of such
libraries.

I searched "indefinite length integer". I don't see any C++ libraries
in the first a few pages.

how about searching for "arbitrary precision integer c++"?

GMP has a nice C++-Class-Interface
