Fix error in Dot().

Thanks for noticing that. I never used it anywhere, so it was a tough one to find. I will merge immediately.

No problem! Another thing to note is that inline constexpr for a function is redundant since C++17.
Reference: https://en.cppreference.com/w/cpp/language/constexpr

Either way, cool work so far. I would like to contribute more, but probably won't have much time with the school year starting.

Yes I know about the redundant inline-s, it's just that I learned it after I wrote those functions and it is like a practice to me now. I am working on a new update, and I guess it's time for a contributors section in the readme. I will add your name on the top of the list.

I guess it will affect me too, but here school will start in November.
Thanks for all, seriously.

Everything good.

Great! See you on the other side of the school semester.

[TerensTare]

I will be there.
