Eric Barnhill commented on NUMBERS-10:
--------------------------------------
I would also add, as I am working to conform to c++11 standards now, that in
c++11, there is a method polar(). However, this is only to construct a complex
from polar coordinates, and not to return one. This makes me think the C++
working group struggled with the same headaches, and came to the same solution,
however reluctantly.
> Revamp "Complex" representation ?
> ---------------------------------
>
> Key: NUMBERS-10
> URL: https://issues.apache.org/jira/browse/NUMBERS-10
> Project: Commons Numbers
> Issue Type: Wish
> Reporter: Gilles
> Labels: API, design, review
> Fix For: 1.0
>
> Attachments: CartesianRepresentation.java, Complex.java,
> MixedRepresentation.java, PolarRepresentation.java
>
>
> This is a proposal to enhance the internal representation of complex numbers.
> The purpose is to allow usage of both cartesian and polar representations,
> with the aim that calculations are performed (transparently) with the one
> that will be more accurate and/or faster.
> The API would certainly be improved, from
> {code}
> final Complex c1 = Complex.valueOf(1, 2);
> final Complex c2 = ComplexUtils.polar2Complex(2, 7);
> final Complex r = c1.add(c2);
> {code}
> with the current code, to
> {code}
> final Complex c1 = Complex.createCartesian(1, 2);
> final Complex c2 = Complex.createPolar(2, 7);
> final Complex r = c1.add(c2);
> {code}
> Please refer to the attached files (they are self-documenting, but of course,
> Javadoc must be added if the proposal is validated).
> Would there be merit in pursuing in that direction?
> Or is there any show-stopper?
