Short little Elixir App that calculates Fibonacci numbers, either as a sequence or a certain number you ask for.
Of course you need Elixir and Erlang running on your system.
Clone the repo, cd in it and fire up iex -S mix
Calculate the first 100 Fibonacci numbers with
Iexfib.fib(100, true)
or grab just the 55th Fibonacci number with
Iexfib.grab_fib(55, true)
