Or awk. For some problems, awk is fantastic.

If you want arbitrary precision, use bc (or a programming language with an arbitrary precision math library). POSIX shells in general may use smaller integers than that. I wouldn't expect anything outside the range (-2^31 .. +2^31) to be portable. expr(1) is legacy rubbish and should never be used in new scripts.
