25,709,429 | In my Qt app I'm trying to pass a large integer value from my C++ code to QML.
In my C++ I have a Q\_PROPERTY(int ...), but apparently int sometimes isn't enough for my app and I get an overflow.
Can I use long types or unsigned types in QML? How about dynamically sized int types?

] | I find your question interesting because it looks trivial initially, and though raises many points in the way to get an answer.
I assume that you want to pass a 64 bit integer from C++ to QML. I explain later why.

If you are on a 32bit system, the unsigned int would get you from 0 to 4,294,967,295.

Instead, it will yield a value and let forget it, then yields the next, and so on. Here, I'll use your code and do a simple tweak to change list into a generator. You could just use `()` instead of `[]`.

] | Firstly, you correctly found the discriminant:
$$D = B^2 - 4AC = [-(2+i)]^2-4(-1+7i) = 7 - 24i.$$
Then:
$$x\_{1,2} = \frac{-B\pm \sqrt{D}}{2A}=\frac{2+i\pm\sqrt{7-24i}}{2}.\tag{1}$$
But:
$$\sqrt{7-24i}=\pm(4-3i).$$ Why?
Let $\sqrt{7-24i} = z\implies z^2 = 7-24i$.
If we let $z = a+bi \implies a^2-b^2 +2ab i = 7-24i $. ... | HINT

Write $7 - 24\iota $ in the $r e^{\iota \theta}$ form, where $r = \sqrt{7^2 + 24^2}$ and $ \tan{\theta} = -\frac{24}{7} $. Note, $\theta$ will be in 4th quadrant. |
