Hi,
I am currently implementing a solver for linear optimization problems
using the revised simplex method and I stumbled accross some strange
behavior regarding the treatment of the number 0.
I am not sure whether this is compiler or language related though.
The first problem is, that there are two representations of zero, namely
+0 and -0. Does IEEE for floating points allow this? Maybe I didn't
activate IEEE floating point numbers?

action is taking place. Very simple:

Hello all,
I have a question that concerns how C++ input streams (istream, ifstream, istringstream, etc.) behave using the extraction (>>) operator when at the end of a stream's contents.
For instance, I have an input file which is just a one-line string: "do_stuff 20060101 " (yes, that is a trailing space)
I'm using a parse function that attempts to extract a string ("do_stuff") and a long ("20060101") by using some code roughly...

I have a somewhat flippant question regarding undefined behaviour. Does
an operation which invokes undefined behaviour affect the whole program,
or are earlier statements guaranteed to execute correctly?
For example:
#include <stdio.h>
int main(void) {
int i;

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...
