I looked at this a while ago because I was annoyed about stupid implementations of Fibonacci. I quickly noticed that the value of Fn quickly overflows fixed precision datatypes so as you point out you can't use fixed precision arithmetic and have to take account the non-trivial complexity of your operations.
I looks at the real complexity for Binet's formula and implement the better identity used by GMP
F2k = (Fk+1)^2 − (Fk−1)^2
