How to extract WRF fill_value

[HragN]

A simple question that I haven't been able to find on the forums is:

How do I extract the fill_value used in to fill in values in the wrfout files?

There doesn't seem to be a variable or attribute that has the fill value used by WRF, so the only way I get it is through wrf-python command

import wrf
wrf.default_fill(np.float32)

All variables in wrfout must have physically meaningful values. It is not allowed to have filled values in wrfout files.
