Generate the Fibonacci sequence — any number of terms, starting from any position. Big numbers supported.
Each number is the sum of the two before it, starting 0, 1, 1, 2, 3, 5, 8, 13, … It appears throughout mathematics and nature.
Yes. It uses exact big-integer arithmetic, so even the 1000th Fibonacci number (over 200 digits) is computed precisely with no rounding.
It skips ahead so the list begins at the term number you choose — handy if you only want, say, terms 50 through 60.
