I am starting to use templates and have managed to figure out how to use
std::string, std::map and make_pair successfully so far (Yeah I know -
not much of a big step but I'm getting there)
Previously I was using something like:
char *buffer;
double value = 10.5;
sprintf(buffer, "text %.2f text", value);

I am using the std::setprecision function to format variables of type
double in a string however I am unsure how to stop this appearing in
scientific notation.
For example
std::stringstream buffer;
buffer << setprecision(1) << 40.0 << "° C";

Is it possible for me to record floats in a std::stringstream with
100% accuracy? If so how?
Here's a little prog that demonstrates how the default ss loses
accuracy

#include <iostream>
using namespace std;

I use Microsoft Visual Studio C++ 2003 .net 7.1.3088
I have a very large "solution" (1 million lines of code) with about 60
"projects". I use fast solution build to prevent slow "up-to-date" checks
and get incremental linking.
I occasionally add the following debug code to a particular file:
#include <iostream>
#include <iomanip>

I'm having some cases where setprecision in combination with iostreams
gives some unepected behavior. Consider the following program:
#include <iostream>
#include <iomanip>
int _tmain(int argc, _TCHAR* argv)
{
float value = 0.063397526741027832;

Hi,
I setprecision to be 100 for both cases. I'm wondering why the number
of digits are different.
Also, for a double number, I think any digits that are longer than 15
(or 16) are not meaningful, because it exceed the double number's
precision limit. Even if I setprecision to be 100, shall it truncate
the number to be of 15(or 16) digits?

I'm not 100% sure whats even going on, but I'm working on a C++ assignment for school, and its a road trip program

char const METRIC = 'M'; // Input read as metric
char const ENGLISH = 'E'; // Input read as english
char const QUIT = 'Q'; // Input read to quit program
char const QUIT2 = 'q'; // Input read to quit program

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,...

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.

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...
