These exist for a reason!

Double.isNaN(double)
Double.isInfinite(double)

Calling two negatively phrased language-dependent methods is better than one comparison? If there were an isFinite() method, I would consider using it.

Better than using x==x, which seems hacky and is surely platform/implementation dependent. It's better not to introduce hard-to-diagnose bugs in your code.
