perl5-5.36.1_1 package contains bignum/bigint/bigfloat modules which work incorrectly with printf/sprintf. Test script:

------------------------------
#!/usr/bin/env perl

use strict;
use warnings;
use bignum;

my $a = 0.1;
my $b = sprintf("%0.1f", $a);
print "$a = $b\n";
------------------------------

Expected output is "0.1 = 0.1".
Actual output is "0.1 = 0.0".

Workaround:
pkg install p5-Math-BigInt
The package provides new versions of bignum/bigint/bigfloat modules.
