I was hoping to book some rail travel from Vancouver to Seattle, but sadly there were NaN reserveable coach seats available ...

I think it is worse than that; NaN people have already reserved seats.

I thought they introduced bug in calculations, hence got - "Not a Number".

Assuming that they are not selling tickets for for less an a whole seat, should the result of any calculation ever be a floating point value?

It't the number of people that is a floating‑point number, some of them not being all there.

You can still try to divide an int by zero though. Doesn't that still give NaN?

Nope, only floats. And in particular 0 / 0.0; changing first operand to positive > 0 gives infinity, to negative minus infinity. Maybe there are more cases for NaN though, don't know.

Since it is MD fora here, I'm free to assume what I want You might cannot buy half of a seat, but you can calculate how much it costs

NaN is defined as 0.0 ÷ 0.0. You can get NaN from various functions e.g. Math.sqrt(−1).

Naan, a flatbread that I usually associate with Indian food. And completely delicious!

Unless you got for something like a Peshwari naan, you are better off with chapattis.
 
It is sorta covered in the JavaRanch Style Guide.
