Subject: [ruby-core:83193] [Ruby trunk Bug#13992] Strange behaviour for	kernel#integer method

Issue #13992 has been updated by zverok (Victor Shepelev).


Yes, it does. Leading zero designates octal number (base 8), which can't have digit "8" in it.

Bug #13992: Strange behaviour for kernel#integer method
https://bugs.ruby-lang.org/issues/13992#change-67136

* Author: Ursus (Ivan Lasorsa)
* Status: Open
* Priority: Normal

* Target version: 
* ruby -v: 2.4.1
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
I tried this one with ruby 2.3.1 and ruby 2.4.1.

~~~ ruby
Integer('04')
4
Integer('05')
5
Integer('08')
ArgumentError: invalid value for Integer(): "08"
Integer('09')
ArgumentError: invalid value for Integer(): "09"
~~~

Does this makes sense?
