In Java, what happens if you use Double.NaN in an operation?

Question

I have compiled code that erroneously tries to add a number and Double.NaN. I'm wondering if it's throwing an exception that's not getting caught? Does anyone know how that situation is handled?
Thanks.

Answer 1

Adding a number to NaN gives NaN. It isn't expected to cause an exception. I understand that this conforms to IEEE 754.
