I have discovered a math error in the .NET framework's Log function. It
returns incorrect results for varying powers of 2 that depend on whether the
program is run from within the IDE or from the command line. The amount by
which the calculation is off is very small; even though the double data type
holds the errant value, it seems to round off when printed (via ToString())
and shows the correct one. The problem is that the errant value is...

No, not a question about "banker's rounding" or whatever it's called.
I want to round a double to the nearest 100th, so I perform the
following:
// original is a double
double result = Math.Round( original, 2 );
But I'm not happy with the results. E.g. if original is

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?

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

The folllowing will round to 526, but it should round to 527. It works
correctly for all other numbers, except for this one. Does anybody know of a
bug in Math.Round?
Dim ldecWater As Decimal = 526.5
CType(Math.Round(ldecWater, 0), String)

Math.Round has good behavior as following:
Math.Round(3.45, 1); //Returns 3.4. The last '5' is thrown away because 4 is
even
Math.Round(3.75, 1); //Returns 3.8. The last '5' is used because '7' is odd
However, if format.NumberDecimalDigits is 1
decimal d = 3.45M;
d.ToString( "F", format ); //Return 3.5 - this is different from Math.Round;

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,...

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...
