【注：ネタ】Ruby言語における整数型の最大値と最小値の変遷（しません）

諸事情でかくかくしかじか、とにかく飲み込んでくれ、という状況なので、まぁ今のうちに2019年を振り返っておきますか、ということで。

（※先に断っておきますと、「子どもじゃあるまいし・・」という突っ込みをしたいと思いますが、『心は永遠の幼児』ですので。）

振り返ってみると、面白い画像が出てきました。

まさかねぇ、とツイート検索してみたら、未だに残ってるんですねぇ（2019/12/25 00:22現在）‥ということで、以下が元ツイート。

2017でRuby2.0.0で比較されてもという気分ではある / “215116” https://t.co/b7pePacUpB

単に整数型の最大値と最小値を調べているだけなんですけどね。確かに、2017年にRuby 2.0.0というバージョンは「古いもの」なのでしょうが、CentOS 7のベースリポジトリに含まれる正統派バージョンなのですよね。

「Ruby 2.0.0というバージョン番号に脊髄反射しただけ」なのか、「突っ込む先を間違えただけ」なのか、「全世界35兆人(!?)のCentOSerを敵に回したいだけ」なのか、はたまた「常に新しいバージョンを実運用で維持し続けられるほどのヒ・マ・人」なのか、まぁ真意は知りませんけど。

Rubyがバージョンによって整数型の最大値と最小値が違うクソ言語ではないことを願って、時間もないので、一気に行ってみましょうか。

使うプログラムは前回のものをちょっと弄って以下です。

if defined?(RUBY_DESCRIPTION)
    print RUBY_DESCRIPTION,"\n"
else
    print RUBY_VERSION,"\n"
end
a = 1
ct = 255
a <<= ct
while ct < 256 && (a << 1) + 1 > a
    a <<= 1
    a += 1
    ct += 1
end
print "    int:max? = ",a,"\n"
a += 1
print "          +1 = ",a,"\n"

a = -1
ct = 255
a <<= ct
while ct < 256 && (a << 1) < a
    a <<= 1
    ct += 1
end
print "    int:min? = ",a,"\n"
a -= 1
print "          -1 = ",a,"\n"

ウザくなるので、256ビットシフト位で止めておいてあげましょうか（十分ウザい）。

では結果。

「ruby 2.0.0p648」が2回出てくるのは、yumでインストールしたものとソースからビルドしたものの2つがあるためです。 また、現在「ruby 2.7.0rc2」まで出ているようなので、そこだけpreview版とrc版も実行しました。

こんな感じですかね？

ではよいお年を。
