Subject: [ruby-core:31685] [RubySpec #3684] String#to_i documentation mismatch

RubySpec #3684: String#to_i documentation mismatch
http://redmine.ruby-lang.org/issues/show/3684

Author: Sakuro OZAWA
Status: Open, Priority: Low
Category: DOC, Target version: 1.9.1 RC2

Missing:

Giving base 0 makes this method take prefix into account.
ex. "0xFF".to_i(0) #=> 255

Wrong:

string.c rb_str_to_i says:

 This method never raises an exception.

But it raises

* ArgumentError when the given base is out of range
* TypeError when converting the base into Integer is failed

 % ruby -ve '"123".to_i(99)'
 ruby 1.9.2dev (2010-07-11 revision 28618) [x86_64-linux]
 -e:1:in `to_i': invalid radix 99 (ArgumentError)
         from -e:1:in `<main>'

 % ruby -ve '"123".to_i(nil)'
 ruby 1.9.2dev (2010-07-11 revision 28618) [x86_64-linux]
 -e:1:in `to_i': no implicit conversion from nil to integer (TypeError)

 % ruby -ve '"123".to_i(false)'

 -e:1:in `to_i': can't convert false into Integer (TypeError)
         from -e:1:in `<main>'
