in that case I would recommend MPFR (www.mpfr.org). Other floating-point
packages with accuracy guarantees are NTL's RR class in binary, Maple and
decNumber in radix 10 (although only for the 4 basic operations in Maple).
As for speed, you'll find a detailed comparison on

Depending on your exact needs, you can also use (arbitary precision) interval
arithmetic libraries, like for example MPFI, which is based on MPFR.
