Thank you for your reply. I understood that there is no documented specification and the current implementation. How should Integer method behave for this case? My thought is that Integer method should convert a Delegator object like when a String is given. Because of this, I override Integer method like below in my project. ```ruby module Kernel alias_method :__orignal_Integer, :Integer def Integer(arg, base = 0, exception: true) arg = arg.__getobj__ if arg.is_a?(::Delegator) __orignal_Integer(arg, base, exception: exception) end end ``` ---------------------------------------- Bug #18998: Kernel#Integer does not convert SimpleDelegator object expectly https://bugs.ruby-lang.org/issues/18998#change-99102 * Author: taichi730 (Taichi Ishitani) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- Kernel#Integer method doens not convert a SimpleDelegator object of which value is a String. This is an sample code. ``` ruby require 'delegate' p Integer(SimpleDelegator.new('0x10')) ``` I expect Kernel#Integer to convert the input value as a String and the expected returned value is `16`. Hoever the actual returned value is `0` so it's seemed that `#to_i` method is just called. ``` taichi@LAPTOP-TVTKLNFD:temp $ cat test.rb require 'delegate' p Integer(SimpleDelegator.new('0x10')) taichi@LAPTOP-TVTKLNFD:temp $ ruby test.rb 0 ``` Which is the correct behavior? -- https://bugs.ruby-lang.org/ Unsubscribe:
