I had a problem with string which have some \ chars at the end of the
string. For example:
$String = "I want this **** out of here\\\\\\\\\";
I needed to remove it useing regular expression...i thinked that
something like "/\\+$/" is enough but i was wrong. I made some tries
and finaly i removed "\" chars it with "/\\\+$/". It works (i'm proud
with myself :)), but i can't understand why \\\ matchs single \, and \\

I need to implement a function to implement the rounding of floating point
values. At the moment i have two different implementations, depending on the
type of the return value (integer or double).
// Integer calculation (fast)
int iround(const double x) {
return (x>=0 ? static_cast<int>(x + 0.5) : static_cast<int>(x + 0.5)
}
// Floating point calculation (slow)
double dround(const double x) {

I have a saved query from which I build my weekly customer reports. It
queries a "Region" column which has predefined values: North, South etc.
With this same query I would like to quier one more column called "Round"
which has NON-predefined values. So when I double click on the query a
window should popup asking me what value would I like to enter for the
"Round" column. How do I do that?

I am writing a program for a C++ class and I need to be able to round my numbers up to the nearest 1000 (not 1000th, the actual number 1000). For example, if my variable value came back as 325, I would need a function to round it to 1000, if the variable came back as 1555, I would need to round to 2000. Any suggestions? Other than floor and ceiling functions, which do not appear to apply in my case, I cannot find any functions available in...

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;

Hey everyone, as I have been by far pleased with some of the top helpers on this forum, I have decided to send another one your way.
Even though I am personally having minimal issues with this script I have developed, I am wondering if someone could fix my little bug with 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:

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,...
