Math::BaseCalcで16進数以外の基数変換

31進数で出力する必要があるらしいので...

#!/usr/local/bin/perl
use strict;
use utf8;
use Math::BaseCalc;

main();

sub main {

    my $base_31 = Math::BaseCalc->new(digits=>[0..9,'A'..'U']);
    print $base_31->to_base(0),"\n";
    print $base_31->to_base(1),"\n";
    print $base_31->to_base(10),"\n";
    print $base_31->to_base(31),"\n";
    print $base_31->to_base(32),"\n";
}

実行結果

$ ./foo.pl
