Is floating-point math consistent in C#? Can it be?
...g floating point operations. Most information is probably specific to C or C++, however.

A note on fixed point
Binary fixed point numbers can also work well as a substitute for floating point, as is evident from the four basic arithmetic operations:

If you want to do this the C++ way, do it like this:
#include <fstream>
#include <iterator>
#include <algorithm>
int main()

std::ifstream input( "C:\\Final.gif", std::ios::binary );
std::ofstream output( "C:\\myfile.gif", ...
Why is f(i = -1, i = -1) undefined behavior?
...ans a type like a int, float, or a pointer (see What is a scalar Object in C++?).
Second, it may seem more obvious that
f(++i, ++i);
would have undefined behavior. But
f(i = -1, i = -1);
is less obvious.
A slightly different example:
int i;
f(i = 1, i = -1);
std::cout << i <<...
What is the strict aliasing rule?
...ably has instructions to load buff's contents. Then again, maybe you're in C++ and this is some templated header only implementation that the compiler thinks it can inline. Or maybe it's just something you wrote in your .c file for your own convenience. Anyway undefined behavior might still ensue. E...
When to use std::begin and std::end instead of container specific versions [duplicate]
...ld probably use c.begin() due to inertia. I would expect new text books on C++ to recommend the free function version (as it is never worse and sometimes better), but that has to catch up with common usage.

What are the differences between Clojure, Scheme/Racket and Common Lisp?
... Scheme :)
In fact allot of software some folks think might be written in C++ was probably done under the Lisp umbrella, its hard to pick out the golden apples out of the bunch. The fact is C++ was not always popular, it only seems to be popular today because of a history of updates. For the lesser...
How does BLAS get such extreme performance?
... block.
For purely numerical tasks, Fortran is pretty much unbeatable, and C++ takes a lot of coaxing to get up to a similar speed. It can be done, and there are a few libraries demonstrating it (typically using expression templates), but it's not trivial, and it doesn't just happen.
