Hi,
The algorithms for cubics and quadratics come from Numerical Recipes
(3rd ed.), and the quartic problem is internally reduced to a cubic and
two quadratics, using well-known standard tricks.
Nice, wll documented code.
Just to be sure you are on safe ground, you took the *algorithms* but no *code* from Numerical Recipes, right? They are pretty clear about their licensing, see

Yes, the code is original (written from scratch), only the algorithms
come from the book.
