FIBO - maccergit/Rosalind GitHub Wiki

Investigation into computing Fibonacci numbers has been extensively covered on the corresponding problem page for Project Euler. As noted there, the iterative approach is very fast - and a closed form is also available. The closed form version provided here uses Python float values with no special code to address the floating point issues noted in that page - see that page for an in depth investigation into issues associated with computing very large Fibonacci numbers.
