I've released a new version of DecInt that fixes a bug in multiplication. Anyone using version 0.3b or earlier should upgrade.
DecInt implements fast arithmetic on large decimal integers. For example, it can calculate the decimal representation of the largest Mersenne prime, all 7816230 digits, in just a few seconds. I've also compiled processor-specific binaries of GMPY. I have versions for AMD 32-bit processors and Intel Pentium 4 processors. The Pentium 4 version is approximately 4x faster than the default version of GMPY. DecInt and the experimental GMPY binaries are located at http://home.comcast.net/~casevh Enjoy, casevh -- http://mail.python.org/mailman/listinfo/python-list
