Fibonacci Sequence Calculator
Fibonacci Sequence: a planned Super Calculator tool. Covers term index n. Stub page: the tool, its formula and a worked example are not published yet.
Fibonacci Sequence Calculator is a planned calculator in the mathematics section of Super Calculator, covering algebra and number theory.
What this calculator will compute
Inputs: term index n, starting values and number of terms to list.
Outputs: nth Fibonacci number, term list, ratio of consecutive terms approaching phi and sum of the first n terms.
Formula, recorded as scope and not yet verified against a primary source: F(n) = F(n-1) + F(n-2) with F(0) = 0 and F(1) = 1. Closed form by Binet’s formula F(n) = (phi^n - psi^n)/sqrt(5), exact only up to about n = 70 in double precision. Fast doubling gives exact BigInt values in logarithmic time.
