Bug #11648

Undocumented features of String#oct

Added by mwpastore (Mike Pastore) about 9 years ago. Updated almost 9 years ago.

Status:
Closed
Target version:
-
ruby -v:
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]
[ruby-core:71310]

Description

String#oct will adjust the base of the stringy number being converted to 2 (if prefixed with 0B), 8 (also the default, if prefixed with 0O), 10 (if prefixed with 0D), or 16 (if prefixed with 0X). Much to my surprise this behavior is not documented at ruby-doc.org [1]. Is this the intended behavior and if so should the documentation be updated? If it is not the intended behavior, perhaps String#oct should raise an exception if someone tries to use this undocumented feature?

It is surprising for me too. But this behavior was introduced in r373 by intention.
I hope Matz remembers the original intention.

I guess Ruby followed the behavior of Perl and it was useful to handle string representation of file permissions?
