Ah, part of the secret is to use print! I was using say and not get

Thanks, Laurent!

Sure Tom,
for example, let's print the first 200 digits of pi.
Since I am getting about 1.2 * $n correct digits for a 0..$n range when
calling the plouffe subroutine, it is sufficient to use the 0..200 range to
get (more than) 200 correct digits.
sub plouffe (Int $k) {
my $result = (1.FatRat

Laurent, now that you have
Yes, Brian, you're right, it seems that it is enough to use a FatRat for
the first term, even with an integer input of 400. Thank you very much.
Quite likely because the first term's denominator is the only one that is
growing very fast with an exponentiation, 16 ** $k, while the others only
have
Thank you very much, Fernando, I'll try that as soon as I get back home.
Cheers,

This one works fine:
sub plouffe (Int $k) {
my $result = 1.FatRat * (1 / 16 ** $k).FatRat * ((4 / (8 * $k +
1)).FatRat - (2 / (8 * $k + 4)).FatRat - (1 / (8 * $k + 5)).FatRat - (1 /

I guess that until a certain point all the terms not sp
Hello,
in the context of the Perl Weekly Challenge, I was trying to use one of
Franco-Canadian mathematician Simon Plouffe's formulas to compute the
digits of pi.
For this, I have written the following subroutine:
sub plouffe (Int $k) {
my $result = (1 / 16 ** $k) * ( (4 / (8 * $k + 1)) -
