Subject: [ruby-core:91775] [Ruby trunk Misc#15654] Documentation for Complex is wrong or misleading
Date: Mon, 11 Mar 2019 12:02:28 +0000 (UTC)	[thread overview]
Message-ID: <redmine.journal-77052.20190311115559.6fcffd4eae0fdffd@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-15654.20190311084336@ruby-lang.org

Issue #15654 has been updated by nobu (Nobuyoshi Nakada).


There would be a chance to optimize such expressions, but it is not a single literal syntactically, and constant folding is disabled in Ruby for its dynamic nature.
New literal syntax will be needed for an (impurely) imaginary number literal, but I doubt that we really need it.

Misc #15654: Documentation for Complex is wrong or misleading
https://bugs.ruby-lang.org/issues/15654#change-77052

* Author: sawa (Tsuyoshi Sawada)

* Priority: Normal

----------------------------------------
The documentation for `Complex` https://ruby-doc.org/core-2.6/Complex.html says or implies that a complex can be created by literal like `2+1i`, but that is actually calling the method `+` on receiver `2` with argument `1i`. The description should be changed to make it clear that `2+ 1i` is not a literal but is applying a method.
