Bug #3684: String#to_i documentation mismatch

• Status: Closed
• Assignee: -
• Target version: 1.9.1 RC2

[sakuro (Sakuro OZAWA)]

=begin
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]
