I don't think so, but it shouldn't return a zero either.
That call should mean: scan this whitespace separated string for as many
floating point numbers as it has. There are none, so it should return
and empty array:
array([], dtype=float64)
fromstring() needs some work in a few other ways -- see my message a
couple days ago.
Does anyone want to work on fromstring()? I'd like to , but my C skills
are weak, so I could use some help.
