Playing around with some additional math functions and testing. I know I'm probably not doing the testing entirely correctly, or at least my naming of the tests sucks. Would love feedback, though of course I'll be doing research on it. With the addition of cmpf, Vector is clearly intended to be used with a floating point type, float, double, or long double. I may or may not change this. In my commercial ready version the class would support virtually any type, even a custom number class (fixed point).
