I need to do this (convert double to string) fast, safe and
portable. Is there any way to do this ?
Except the ways following:
1. C++ I/O stream, stringstream (and boost::lexical_cast)
2. sprintf (and its brothers)
3. any nonstandard C/C++ functions

Hi,
I am trying to convert a double to a string. The problem the value of
the double may vary and I need to always the exact value without the
exponential and without rounding.
Example: double 0.00000000000000000000023 should be string
0.00000000000000000000023 and not 0.00 or 2.3-E24
I tried it with
Console.WriteLine(dd.ToString("X", CultureInfo.InvariantCulture))

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'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.
