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 "norm()"

> Key: NUMBERS-64
> URL: https://issues.apache.org/jira/browse/NUMBERS-64
> Project: Commons Numbers
> Issue Type: Task
> Components: complex
> Reporter: Gilles
> Priority: Minor
> Labels: API
> Fix For: 1.0
>
>
> 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.
