> Calculate isNan and isFinite in Complex constructor

> Key: MATH-276
> URL: https://issues.apache.org/jira/browse/MATH-276
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 2.0
> Reporter: Mark Anderson
> Priority: Minor
> Fix For: 2.0

> Attachments: Complex.patch

>
> From profiling some code performing a large number of FFT operations I found
> that due to isNaN being called as part of complex arithmetic a large
> proportion of time was spent within isNaN.
> I would propose calculating isNaN and isFinite in the constructor to save
> calculating these values each time the methods are called.
