How can I check if assignment of a float to a double (or vice versa)
will result in loss of precision?

I've been trying to perform a calculation that has been running into
an underflow (insufficient precision) problem in Microsoft Excel, which
calculates using at most 15 significant digits. For this purpose, that
isn't enough.
I was reading a book about some of the financial scandals of the
1990s called "Inventing Money: The Story of Long-Term Capital Management
and the Legends Behind it" by Nicholas Dunbar. On page 95, he mentions

Hi all,
I had problem regarding float/double arithmetic only with + and -
operations, which gives inaccurate precisions. I would like to know how the
arithmetic operations are internally handled by C# or they are hardware
(processor) dependent. Basic addition operation errors, for ex:
3.6 - 2.4 = 1.19999999999 or 1.20000000003
There are the erroneous values I'm getting. I'm using C#.Net v1.1 Please
reply me how these operations are...

I'm trying to output a double using a precision that
varies, governed by the value of a precision variable.
In C I can do it like this:
double pi = 3.14159;
int prec = 4;
printf( "%.*f", prec, pi ); // 3.1416
The * in "%.*f" says to use the value of the next

Hi folks
I wrote the naive program to show up the unit roundoff (machine
precision) for single and double precision:

Dear all,
I want to do multiprecision floating point, i.e. I want
to go beyond single precision, double precision and have
quadruple precision, octuple precision and the like,
and possibly with high speed.
What would be the possible alternatives?
Thanks for any help

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...

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,...

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...
