Hi,
I'm having problems to successfully execute the test scripts on a
Compaq host ( OSF1 tr51bdev V5.1 2650 alpha ). Almost all tests end up
with the following error message
"PARI: *** Invalid arguments to divll. at test_eng/Testout.pm line
30.
...propagated at t/polyser.t line 9.

I have a quick question about the math library included in the standard
C90 (and 99).
The gcc, xlc and possibly other compilers/linkers on some unix
platforms cannot use any math functions in math.h if a switch (-lm) is
used, so *explicitly* having the linker use a file called libm.so or
libm.a/dylib/whatever.
Is it true on all the platforms? (answer: probably no)

I was considering C# for developing a scientific application, but I have
noticed a ~30% difference between VC++ .NET and C# on the same machine,
under identical conditions:
double a = 0,b = 0, c = 0, d = 0, e = 0;
for(int n = 0; n != 6000000; n++)
{
a = n % 5 *2 / 3 - 4 + 6 / 3 - n + n * 2;
b = n * 2.3 - 1 *2 / 3 - 4 + 6 / 3 - n + n * 2;
c = n * 3 / 3.5 *2 / 3 - 4 + 6 / 3 - n + n * 2;

I have just switched from VB6 to vb .net. In Vosual
Studio.net I am missing the reference to System.Math and
can not find it anywhere. I assume is is System.Math.dll.
Where the hell is it?
Thanks,

Just making sure I'm not missing the boat here, but are there any
special routines for doing currency math (fixed precision stuff) in .NET?
The wonderful problems of doing math on decimals tend to shine when
writing accounting software :-)
How are others dealing with this?

Hi, I'm new to this mailing list and fairly new to Python as well. I'm
working on a prototype for a 3D game using OpenGL, and take this
opportunity to learn Python better.
I'm looking for a good library for vector math. I need to do vector
addition, cross products, dot products etc. and probably in the future
I'll need matrix math as well.
So far I've used the Scientific library, which is very nice, but
unfortunately it crashes when I...

I'm writing a portable implementation of the C standard library for
http://www.clc-wiki.net and I was wondering if someone could check the
functions in math.h for sanity/portability/whatever. I'm almost halfway
through writing the over 200 functions needed to implement C99's
version of math.h, and I would like to have some feedback and/or expert
advice on my implementations.
Sincerely, Gregory Pietsch

hi,
My application that contains the .o's that were generated from using
"freeze" needs to import math. The point of using freeze was to make a
static application that can be shipped as a single entity (it contains
the dot o's from libpython2.4.a), vs having to worry about external
python dependencies.
"importing math" as far as I can tell right now, invokes a shared
library (math.so). Now I have a shared library dependency that I...

The cosine function works fine, but I'm getting weird answers for sine.
Is this a bug? Am I doing something wrong?

Hi, I am a very newbie who would very much appreciate some hints.
Python 2.52. on Windows XP for now. Soon on Ubuntu 8
I am teaching myself Python following free tutorials. I can solve

using math libraries nothing seems to work. I downloaded a 2002

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
