Comment (by charris):

 But it isn't consistent in practice. If I start with an int16 array and
 divide by its mean, I get a float64 result. If I divide the same array by
 its means along the first axis, I get a float32 result. This example may
 look artificial, but little inconsistencies like that can lead to
 unexpected behaviour that is hard to track down.
