Benedikt Ritter created MATH-1222:
-------------------------------------

             Summary: Use Double.isNaN(double) instead of x != x in FastMath
                 Key: MATH-1222
                 URL: https://issues.apache.org/jira/browse/MATH-1222
             Project: Commons Math
          Issue Type: Task
            Reporter: Benedikt Ritter


As discussed in http://markmail.org/thread/f6juilawhswblnve we should use Double.isNaN(double) for checking whether a double is NaN in FastMath instead of using the odd looking x != x comparison.
