The cast should be safe, as it's a size_t to a double.  It's just that having
to!double() would have identified a problem, and if the speed hit would be
avoided with the use of -release -noboundscheck I'd have assumed it would be
worth it.

But you're right, the simplest thing to do is to fix the implementation error.

Related note -- what would you anticipate about the speed hit of isNan(x) versus
if(booleanValue) ... ?  Yes, I'll benchmark. :-P
