So this is bigint and not BigInt? Because when I tried doing the same with BigInt, the data hit the ceiling of xffffffffffffffff.

    Math::BigInt implements the code for arbitrary precision. bigint enables that code transparently wherever it is used.

    Show the code. It works for me: 

    #!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

use Math::BigInt;

my $x = 'Math::BigInt'->new('123456789' x 5);
say $x ** 1234;

      That's again my bad. I tried to do a sprintf after the math op using BigInt. BigInt is just fine and I am stupid enough to doubt it.
