----------------------------------------
Bug #8697: Fixnum complement operator issue
https://bugs.ruby-lang.org/issues/8697#change-41012

Author: torimus (Torimus GL)
Status: Rejected
Priority: Normal
Assignee: 
Category: core
Target version: current: 2.1.0
ruby -v: 1.9.3p448
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


=begin
By the ((<documentation|URL:http://www.ruby-doc.org/core-2.0/Fixnum.html#method-i-7E>)), bitwise complement operator ((*~*)) to Fixnum instance should do ((*one's complement*)) with just flipping all bits. In fact, current implementation does ((*two's complement*)) due to or-ing with FIXNUM_FLAG, which is defined as 1.

Either fix the documentation or the fix_rev function implementation.
Affected versions: both 1.9.3 and 2.0.0
