  Ah, but way down at the bottom.  Nobody ever looks there.  I've
added material to the top in the next version of the documentation so
it's easier for people to learn about.

  I think it more like this:  If you aren't using complex numbers and
get one by accident (by passing a negative number to something that
normally only takes non-negative numbers, for example!), then you are
probably failing to detect an error in the input data.  I suspect this 
is the more common problem.
