Comment 5 for bug 1622757

Opening an undefined float or int on the booklist already automatically sets the value to zero. The right-click menu does what one expects.

It is true that using the spinner arrows or the right-click step on either bulk or single edit moves from undefined to -999999. I will change this. I say "change" because it isn't actually a bug, but is instead an enhancement.

I don't know what you are referring to when you mention the format.
