i have a question about this, if anyone wants to find the time. How many decimal places of accuracy will perl allow? This algorithm gets more accurate after every iteration, but perl stops at about 10 or 11 places of accuracy and the rest is off, which makes me wonder. It's not obfuscated except for the algorithm...
#!/usr/local/bin/perl -w
use strict;

   my($s,$a)=(5*(-2+sqrt 5),.5);sub a{5/(pop)-1}
   sub b{(a(pop)-1)**2+7}sub c{my$s=pop;(a($s)/2
   *(b($s)+sqrt(b( $s )**2-4*a($s)**3)))**(1/5)}
   sub d{my$s=pop;25/((c($s)+a($s)/c($s)+1)**2*$
        s)}sub e{my             ($s,$a,$m)=
        @_;($s**2*$             a)-5**$m*((
        ($s**2-5)/2             )+sqrt$s*($
        s**2-(2*$s)             +5))}my($x,
        $n)= (shift             ||10,0);do{
        $a=e($s,$a,             $n);$s=d($s
        )}while$n++             <$x;print""
        ,(1/$a),$/;
