Subject: [ruby-core:117481] [Ruby master Bug#18993] Inconsistent Range#size for Float and Rational
Date: Tue, 09 Apr 2024 19:38:10 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-107868.20240409193809.52465@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-18993.20220902181804.52465@ruby-lang.org
Issue #18993 has been updated by jeremyevans0 (Jeremy Evans).
Status changed from Open to Closed
This appears fixed in Ruby 3.3:
```
$ ruby32 -ve "p (5.quo(3)...5).size"
ruby 3.2.3 (2024-01-18 revision 52bb2ac0a6) [x86_64-openbsd]
3
$ ruby33 -ve "p (5.quo(3)...5).size"
ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-openbsd]
4
```
----------------------------------------
Bug #18993: Inconsistent Range#size for Float and Rational
https://bugs.ruby-lang.org/issues/18993#change-107868
* Author: masasakano (Masa Sakano)
* Status: Closed
* ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-darwin20]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
The returned values of Range#size between Rational and Float and also with regard to `exclude_end` of true and false are inconsistent.
The example below highlights the difference. The first and second should return the same value. The difference between the first and third seems strange - if this is the specification, it should be clearly described in the [doc](https://ruby-doc.org/core-3.1.2/Range.html#method-i-size "Ruby-3.1.2 official doc of Range"). This point may be related to the issue "Misc #18984".
```ruby
(5.quo(3)...5).size # => 3
(5.quo(3).to_f...5).size # => 4
(5.quo(3)..5).size # => 4
(5.quo(3).to_f..5).size # => 4
```
