Complex Add and Subtract handle NaN arguments differently, but javadoc
contracts are the same
---------------------------------------------------------------------------------------------
Key: MATH-618
URL: https://issues.apache.org/jira/browse/MATH-618
Project: Commons Math
Issue Type: Bug
Affects Versions: 2.2, 2.1, 2.0, 1.2
Reporter: Phil Steitz
Fix For: 3.0
For both Complex add and subtract, the javadoc states that
{code}
* If either this or <code>rhs</code> has a NaN value in either part,
* {@link #NaN} is returned; otherwise Inifinite and NaN values are
* returned in the parts of the result according to the rules for
* {@link java.lang.Double} arithmetic
{code}
Subtract includes an isNaN test and returns Complex.NaN if either complex
argument isNaN; but add omits this test. The test should be added to the add
implementation (actually restored, since this looks like a code merge problem
going back to 1.1).
