I know; I lose a couple of digits by using float8 instead of numeric, but i=
t's much simpler and faster, and if it returned numeric people would _think=
_ it was exact.
And if we have a cast to numeric, people who want those extra digits can ca=
st to numeric before dividing.
But I do still have the numeric code that I tried, so if that's how people =
want to do it, I can provide it.
