Einstellung Effect

Thanks! It's already approved :)

I've lowered the radius values for C++ random tests, could you try again?

If you're printing doubles in scientific form you should print it to at least 15 digits or something. 6 digits is far from enough to resolve tiny differences.

Rounding function seems ok, maybe the problem is in the rest of your code. I agree the error message isn't helpful in that case.

but the spoiler flag is... :p (comments visible in the dashboard of anyone)

Description updated.

Many thanks! I've done the changes.

"delete &" is not what you want, the & makes no sense there.
The memcpy code is also wrong. You are only copying 1000 bytes, not 1000 ints.
Much simpler:

It(should_work_for_random_tests_n_1000_An_10000) {
        srand((unsigned)time(NULL));
        cout << "<p><font color=\"blue\">n == 1000, a[n] <= 10000</font></p>" << endl;
        int count = 3;
        while (count--) {
            std::array<int, 1000> array;
            for (auto i = 0; i < 1000; ++i)
                array[i] = rand() % 10000;
            Assert::That(don't see this!);
        }
    }

And should you need a copy you can then simply:

std::array<int, 1000> array2 = array;

Any idea about this problem? (I've rewritten the tests using std::array)

My code:

	It(shoud_work_for_random_tests_n_1000_An_10000) {
		srand((unsigned)time(NULL));
		cout << "<p><font color=\"blue\">n == 1000, a[n] <= 10000</font></p>" << endl;
		int count = 3;
		while (count --> 0) {
			auto array = new int[1000]();
			for (auto i = 0; i < 1000; ++i)
				array[i] = rand() % 10000;
			auto _ = *new std::array<int, 1000>();
			memcpy(_.data(), array, 1000);
			Assert::That(don't see this!);
			delete array;
			delete &_;
		}
	}

Which is raising:

Process exited prematurely with a SIGSEGV signal.

Thanks again for your suggestion and help! :D

Shit, the edited codes are lost. Maybe I should try to rewrite one tomorrow. It's 0:00 a.m. in my timezone. I have to sleep.

I'll try, thanks
