Issue #8299 has been updated by JesseJohnson (Jesse Johnson). I'm not able to replicate this in Ruby 2.6 or Ruby 3.2. Has this been fixed in the relevant compilers? If so can this bug be closed? ``` irb(main):001:0> RUBY_VERSION => "2.6.10" irb(main):002:0> -1.1505945E-5 => -1.1505945e-05 ``` ``` irb(main):001> RUBY_VERSION => "3.2.2" irb(main):002> -1.1505945E-5 => -1.1505945e-05 ``` ---------------------------------------- Bug #8299: Minor error in float parsing https://bugs.ruby-lang.org/issues/8299#change-105294 * Author: bobjalex (Bob Alexander) * Status: Assigned * Priority: Normal * Assignee: nobu (Nobuyoshi Nakada) * ruby -v: trunk ---------------------------------------- I encountered a float that either parses [slightly] differently (or converts to string differently) in Ruby than it does in Python or Java. This looks like a Ruby bug since the result "looks" incorrect. It is easily reproduced by entering the magic number (-1.1505945E-5) into irb. It behaves the same in 2.0 and 1.9. I'm using Windows. Below is an irb session that demonstrates. Also included are JRuby and Python trials that show better behavior. This issue is not causing me any problems, but just in case someone there is interested in looking into it... Bob
