Assignee set to matz (Yukihiro Matsumoto) ---------------------------------------- Bug #16470: Issue with nanoseconds in Time#inspect https://bugs.ruby-lang.org/issues/16470#change-83585 * Author: andrykonchin (Andrew Konchin) * Status: Open * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: * ruby -v: 2.7 * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- Recently in Ruby 2.7 nanoseconds were added to a string representation produced by the `Time#inspect` method. I encountered an issue when was working on new specs for the RubySpec project - nanoseconds are displaying like a Rational. Let's illustrate it with example: ```ruby t = Time.utc(2007, 11, 1, 15, 25, 0, 123456.789) t.inspect # => "2007-11-01 15:25:00 8483885939586761/68719476736000000 UTC" ``` But nanoseconds are stored correctly: ```ruby t.nsec # => 123456789 t.strftime("%N") # => "123456789" ``` So `123456789` is formatted as `8483885939586761/68719476736000000` which equals `0.12345678900000001`. I assume it isn't expected behavior and will be fixed. -- https://bugs.ruby-lang.org/ Unsubscribe:
