Find index of fibonacci number
WebAs shown here, the (rounded) index n of a given Fibonacci number F is calculated with. n ( F) = ⌊ log φ ( F ⋅ 5 + 1 2) ⌋, where. log φ ( x) = ln ( x) ln ( φ) = log 10 ( x) log 10 ( φ). Now … WebTo expand a bit on J.M.'s comment, the idea is to (1) find an n such that F n ≤ x ≤ F n + k for some small k - i.e. you want your first guess to be good - (2) use the matrix multiplication method to compute F n and F n + 1 and (3) if you haven't hit x yet, then just keep computing F n + 2, F n + 3, …, F n + k until you hit x – kahen
