Formula and methodology
Formula: F0 = 0, F1 = 1, and Fn = F(n-1) + F(n-2).
The Fibonacci sequence is defined by an integer recurrence. The result is returned exactly as text so large values are not rounded by ordinary JavaScript numbers.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Index n — minimum 0; maximum 1000
Worked example
| Input | Value |
|---|---|
| Index n | 10 |
F10 = 55.
Assumptions and limits
- Indexing starts at F0=0 and F1=1.
- The index is a nonnegative whole number no greater than 1,000.
- The sequence value is exact; no golden-ratio approximation is used.
