Issue #4891 has been updated by Sakuro OZAWA.


=begin
Just for curiosity's sake, what is expected from Vector[0,0,0].normalize ?

* ((<WolframAlpha|URL:http://www.wolframalpha.com/input/?i=normalize+%280%2C0%2C0%29>)) says: the zero vector cannot be normalized.
* The patch gives Vector[NaN, NaN, NaN].
* returns (dup of) self?
* domain error?
=end
