Whole number from 0 to 10,000.
Terms from F₀, up to 100.
التفاصيل
Sequence from F₀
0, 1, 1, 2, 3, 5, 8, 13, 21, 34
Fₙ = Fₙ₋₁ + Fₙ₋₂ for n ≥ 2. Values are calculated exactly; no floating-point rounding is used.
كيفية الاستخدام
The Fibonacci sequence starts F₀ = 0, F₁ = 1; each following term is the sum of the two before it.
Exact BigInt output is capped at n = 10,000; sequences are capped at 100 terms so the page stays responsive.
الأسئلة الشائعة
What are the first Fibonacci numbers?
Using the zero-based convention, F₀ = 0, F₁ = 1, and each next term is the sum of the two preceding terms.
Are the results rounded?
No. The calculator uses exact integer arithmetic and caps the input so the browser stays responsive.
