I don't need you to handle it, but you're probably the one who's
going to handle it anyway.  "It" being the question of
the fractional millimeters of rain measurement that are
currently present in the data.  (There's 2 decimal points
of precision (1/100th of a mm!) in the data Tabby sent.)

Or we just do something like round the data to the
nearest even mm.
