[jira] [Commented] (NUMBERS-64) Method "norm()"

["Eric Barnhill (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NUMBERS-64?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16381983#comment-16381983 ] 

Eric Barnhill commented on NUMBERS-64:
--------------------------------------

Good catch. This is not what I think of as the norm. Further the link provided above the call to norm() does not link to a method called norm(). It links to a method called cproj(). I vote for removal.

> Method is trivial, not used within the class, and [not standard|https://math.stackexchange.com/questions/285398/what-is-the-norm-of-a-complex-number].
> Should we perhaps remove it?
> However, if keeping it to mimic the C++ standard library, the computation should be implemented directly; currently, it calls method {{abs()}} which entails many unnecessary checks and operations.
> Javadoc links to an unrelated page.
