[ruby-core:51659] [ruby-trunk - Bug #6677][Closed] Bignum#== and Float#== should be symmetric

From: "marcandre (Marc-Andre Lafortune)" <ruby-core@...>
Date: 2013-01-25 05:55:50 UTC
List: ruby-core #51659
Issue #6677 has been updated by marcandre (Marc-Andre Lafortune).

Status changed from Assigned to Closed

Fixed as of r38825.
----------------------------------------
Bug #6677: Bignum#== and Float#== should be symmetric
https://bugs.ruby-lang.org/issues/6677#change-35623

Author: Eregon (Benoit Daloze)
Status: Closed
Priority: Normal
Assignee: mrkn (Kenta Murata)
Category: core
Target version: 
ruby -v: ruby 2.0.0dev (2012-05-25 trunk 35779) [x86_64-darwin10.8.0]


Reading #3429 again, I noticed a related bug (and by the way, thank you nobu for solving that bug!):

I wrote:
"Also, while doing some tests about this I noticed that "bignum == Float::INFINITY" [...], while it should not, as it is always false."

I did not notice it to hang anymore, but the result of #== is asymmetrical:

    irb for ruby 2.0.0 r35779
    > n=2**7830457;nil
    => nil
    > n == Float::INFINITY
    => false
    > Float::INFINITY == n
    => true

I think a Bignum is never infinite.
