Comment(by wenzeslaus):

 Do we have a standard how to represent NaN (''not a number'') in GRASS (as
 a text)?

 For example in Python:
 {{{
 #!python
 >>> a = float('nan')
 >>> a
 nan
 >>> a = float('NaN')
 >>> a
 nan
 >>> a = float('NAN')
 >>> a
 nan
 >>> a = float('nAn')
 >>> a
 nan
 }}}

 (And the same for `inf`.)

 Is it even appropriate that `r.univar` would give NaNs? Wouldn't be non-
 zero return code and a error message more appropriate? (Perhaps not, but
 we should consider the options.)
