in reply to phi div by 0 error

Just for fun, with a recursive definition of the Fibonacci function:

#!/usr/bin/perl use strict; use warnings; use Memoize; memoize 'fibo'; my $val = shift; printf "%.12f\n", fibo($val+1)/fibo($val); sub fibo { my $n = shift; return $n if ($n < 2); return fibo ($n-1) + fibo ($n-2); }

This gives the following result:

$ perl 32 1.618033988750
