#English

As I mentioned in https://bugs.ruby-lang.org/issues/10086#change-48156,

  1. Now that we are able to hundle complex exponents without mathn.

  2. And overriding \ with quo has too much side effect. I suppose we should not implement such a thing in ruby standard library.

  3. Requiring and integrating other standard libraries doesn't make sense.

This is why I think it might be better to make Mathn class deprecated and disabled in the future.

#日本語(すみませんまだ英語が拙く、意図をより正確にお伝えするため日本語も記載させて頂きます)

僕がこちらのissueで述べさせて頂いた通り、https://bugs.ruby-lang.org/issues/10086#change-48156

  1. mathn で実装されている冪乗演算は mathn を用いずとも現在は実現されている事

  2. mathn 内で行われている \quo でオーバーライドする事は副作用が強く、またこの種のオーバーライドが必要な場面は多くなく、必要な場合でも自ら実装する事が多いと推測される事

  3. 各種数学関連のモジュールをrequireする機能もあまり意味を持たない事

以上の理由より、とりわけRubyの標準ライブラリーで現在のmathn を提供する必要を感じません.

よってmathnを非推奨に、ゆくゆくは廃止してしまうのが良いと考えています.

@Hiroshi SHIBATA

I really appreciate you doing what I should do.

It might be annoying question, it's still open?
If so, please let me know why, otherwise could you make it closed?
I just wanna make sure my tickets remains or not.

I'm sorry to your extra trouble : (
