But that's exactly what we don't *want* you to do! Because (unless you
are a numerical wizard) you probably aren't doing the error analysis
needed to avoid the "unexpected extra point" problem due to floating
point inaccuracies. For your own good, we want you to state the count
and let us deliver the number of points you want.
