Status changed from Open to Closed ---------------------------------------- Feature #12953: (Float, Integer, Rational)#round(half: :down) https://bugs.ruby-lang.org/issues/12953#change-61732 * Author: Shyouhei Urabe * Status: Closed * Priority: Normal * Assignee: ---------------------------------------- I learned that The Japanese Ministry of Health, Labor and Welfare requires that the insured burden amount of employment insurance be calculated in round half down mode. Details: http://www.mhlw.go.jp/topics/2005/04/tp0425-2.html Given there is a real-world situation where half-down is actually mandatory, I think we should implement the (currently lacking) `half: :down` option. -- https://bugs.ruby-lang.org/ Unsubscribe:
