Hi all,
I guess it is more of a maths question than a programming one, but it
involves use of the decimal module, so here goes:
As a self-directed learning exercise I've been working on a script to
convert numbers to arbitrary bases. It aims to take any of whole
numbers (python ints, longs, or Decimals), rational numbers (n / m n,
m whole) and floating points (the best I can do for reals), and
convert them to any base between 2 and...

I am writing an assembly that will be used in a suite of
financial applcations. Naturally I must use integer
arithmetic to ensure the accuracy of my calculations and
in the past have used the rational number class
from the Boost libararies. Is there anything out there
like that or for that matter in the framework that I am
missing.
Cheers

Rational Arithmetic
I need a possible representstion of Rational numbers in C using Structures. It has to be a foating-point representatiobn. Each rational number has to represent/store the numerator and denumerator as integers.
Structures like this can be used;
struct Rational{int a, int b}; to represent a number a/b.
Declaration to include Typedef struck Rational Rational;
It should include only operation of addition and...

In this assignment we shall look at a possible representation of rational numbers in java using objects. The java language represents rational numbers using the same representation used for other real numbers. This is the floating-point representation. However as we may all know, floating-point numbers are quite inaccurate. This means that ½ might actually be represented as 0.49998, which may not be good enough for some applications.
In this...

I'm very surprised actually, to see that Python rejected the use of
fractional/rational numbers. However, when I read the PEP, I know
exactly why the proposal was rejected: People compared fractions with
integers, while it should be more fairly compared to floats.
Arguments against:
- When I use the result of / as a sequence index, it's usually an
error which should not be hidden by making the program working for
some data, since 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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
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 particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
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...
