sifukurt has asked for the wisdom of the Perl Monks concerning the following question:
I need some help. I've written a script that will calculate e using Euler's formula. I'm using Math::NumberCruncher to facilitate the factorial process, and Math::BigFloat which should, in theory, allow me to take e out to an arbitrary number of places. However, for some reason it seems to stop after about 320 places, or so. Here is the code:
Any thoughts on how I can get the above script to go beyond the 320odd places?
Thanks for your time, Monks.
use Math::BigFloat; use Math::NumberCruncher; $ = 1; $N = shift  100; $e = Math::BigFloat>new("1"); for ( $i = 1; $i <= $N; $i++ ) { $fac = Math::NumberCruncher::Factorial( $i ); $e += 1 / $fac; } print $e, "\n";
Any thoughts on how I can get the above script to go beyond the 320odd places?
Thanks for your time, Monks.
