I've added to gmpy.sf.net two binary packages of gmpy for Mac OS X 10.4,
one for the Python 2.3.5 that comes with the system and one for Bob
Ippolito's build of 2.4.1. They still need GMP to be previously
installed (I'm told the one that comes with fink works; I installed my
own from sources, from the GMP's site at swox.com), and they're .tar.gz
packages requiring unpacking with tar xzf from the Terminal -- so, not
very Mackish -- but they may still help if you don't want to install
Apple's free and powerful XCode (which IS currently an 800+ MB download,
after all) and still want to play with gmpy's functionality on your
Mac's Python, I hope.
Let me know if there's interest in me eventually doing a better job of
Mac packaging... while I have a hard time getting ahold of Windows
machines, and particularly suitable development systems for them, I _am_
rather full of Macs (& dev systems for them;-)...

Gmpy module was a wrapper of the GNU MP library. It seems that no
evolution is done on this module since 2001. Indeed, Gmpy is not
supported in Python 2.2 nor 2.3.
My question is the following: what is the better replacement solution
for manipulating long numbers. I want to do long numbers
exponentiations. Thanks in advance for your answers.

In the program that follows, I get the following warning message:
collatz_.py:37: RuntimeWarning: tp_compare didn't return -1, 0 or 1
while b>1:
In this case, b is a gmpy.mpz number. The program operates as it should,
which I guess is why it's a warning. Is there some reason why I shouldn't
use gmpy numbers with relational operators? Is this warning something
that can safely be ignored?

Thanks to David Bolen, who did the build, I have been able to make
available a win32 packaging for gmpy 1.0 on python 2.4 alpha 2 (should
work on any later Python 2.4 as well, but I have no way to check it at
all). I can't reach sourceforge at the moment, so I have meanwhile put
the exe file up at:

Users of both gmpy and python 2.4 on windows are invited to dowload and

I have fixed almost all of the outstanding bugreports and feature
request for gmpy: divm doesn't leak memory any more, truediv and
floordiv are implemented for all types, etc -- in the current CVS
version (one thing I must still look at is divm's behavior when its args
are not mutually prime). It currently compiles w/o warnings, and passes
all of its 1040+ tests, w/the current release of GMP (4.1.4), Python
(2.4.2), MacOSX (10.4.3), XCode...

As things stand now (gmpy 1.01), an instance d of decimal.Decimal cannot
transparently become an instance of any of gmpy.{mpz, mpq, mpf}, nor
vice versa (the conversions are all possible, but a bit laborious, e.g.
by explicitly going through string-forms).
I'm thinking about possible ways to fix this, in whole or in part, but,
before I spend more time on this, I was wondering if there's anybody
else who'd be interested -- if so, maybe we...

python 2.5.2

(1) I find that python/gmpy is about 3 times slower than c++/gmp.
Is this the general experience, or am I doing something wrong?
(2) I am unable to understand the following error in conversion from float() to gmpy.mpf() or how to avoid it:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
