From: nobu@... Date: 2016-11-18T07:16:10+00:00 Subject: [ruby-core:78193] [Ruby trunk Feature#12953] (Float, Integer, Rational)#round(half: :down) Issue #12953 has been updated by Nobuyoshi Nakada. Subject changed from (Float, Rational)#round(half: :down) to (Float, Integer, Rational)#round(half: :down) https://github.com/ruby/ruby/compare/trunk...nobu:feature/round-down ---------------------------------------- Feature #12953: (Float, Integer, Rational)#round(half: :down) https://bugs.ruby-lang.org/issues/12953#change-61562 * Author: Shyouhei Urabe * Status: Open * 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:
