To me that was somewhat depreciated by the fact that you can actually calculate n-the Fibonacci number using Binet&apos;s closed form formula (&lt;a href=&quot;http://en.wikipedia.org/wiki/Fibonacci_number#Closed-form_expression&quot; rel=&quot;nofollow&quot;&gt;http://en.wikipedia.org/wiki/Fibonacci_number#Closed-form_ex...&lt;/a&gt;). You will need arbitrary precision arithmetic starting with certain &apos;n&apos; though, as IEEE 754 will not give you correct result.</text><parent_chain></parent_chain></comment><story><title>&quot;The worst algorithm in the world?&quot;</title><url>http://bosker.wordpress.com/2011/04/29/the-worst-algorithm-in-the-world/</url></story>
