If compiling and adding mpexpr to your tcl environment sounds too much like work and you happen to be running Linux or Unix, check out Bignums Fast and Dirty.
TC - I have compiled a Windows stubs-based DLL that works with (at least) ActiveState TCL 8.4.5. It and other Mpexpr distribution information is at http://crone.us/mpexpr/ .
