Pi is hard-coded into the Long Float Library, but you can compute it to one thousand places (and more) just for fun, if you wish (see the last message in this thread). Alg48 includes an arbitrary precision package for the HP-48 as well. But if 34 digits are enough for your needs, then you can try wp34s in DOUBLE precision mode.
