Subject [jira] Created: (MATH-276) Calculate isNan and isFinite in Complex constructor
Date Wed, 17 Jun 2009 09:02:07 GMT
Calculate isNan and isFinite in Complex constructor

                 Key: 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

I would propose calculating isNaN and isFinite in the constructor to save calculating these
values each time the methods are called.
