doonyy, the context was boating so your calculation was needlessly precise
without gaining utility. but I am glad you can calculate square roots in your
head accurately to 21 decimal places.

The rest of us find that "a little over 7 knots" gives us more than enough
precision AND accuracy in the context of boating.

donny, sq rt 50 is easy to do in one's head.

Yeah, you're right!
