[PD] no more Nan display in Pd, why?

howdy, I see you fixed the atom box in the repo, great! But I'd like to
remind you about the same kind of issue still remaining with [nbx].

The number2 GUI ("nbx") has the same bug of not displaying "nan" - where it
used to before (so it's a bug again). But while with the atom box we could
still print "nan" from its output, the issue with number box is that it
outputs the last value, so it's a bit more complicated than just having it
displaying it.

I know I said things about "inf" and number box, but I see I was missing
some stuff, I'll start a new thread about it.
