Passwordless Authentication and Passwordless Security
It’s no secret — passwords can be a real headache, both for the people who use them and the people who manage them. Over time, we’ve created hundreds of passwords, it’s easy to lose track of them and they’re easily compromised. Fortunately, passwordless authentication is becoming a feasible reality for many businesses. Duo can help you get there.

I tried to use this to alleviate numerical stability issues with some matrix computations. However using Big<1,2> instead of double turns fraction-of-a-second computation into multi-hour computation (or more, I stopped the computation after a couple of hours). I also found out that a lot of standard operators are missing, e.g.: Big operator*(double, Big) Big operator*(int, Big) etc... even though operators involving only Big type are implemented, e.g.: Big operator*(Big, Big). Strangely, Abs(), Sqrt() etc do not work on a copy but on the parameter itself, thus instead of Big positiveA=A.Abs(); the following code is required: Big positiveA=A; positiveA.Abs(); Lastly, casting to int doesn't work: int(Big) //compile error //http://www.learncpp.com/cpp-tutorial/910-overloading-typecasts/ Bottom line: For some less computationally demanding scenarios, I guess this class is useful.
