I'm trying to create a function that will turn a float into a
std::string that always shows the number to two decimal places. I have
the following but it doesn't give the desired output:
inline std::string ftos(float f)
{
std::ostringstream buffer;
buffer << std::setprecision(2) << f;

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";

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 All,
I am new to C++ programming. I encounter an unexpected behavior of
'setprecision'.
The code snippet is :
#include <iostream.h>
#include <stdio.h>
#include <iomanip.h>

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?

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...

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...
