Dear M. Joseph Rheubeck,

In the last line of my example, the lower case digits are not significant on an operational standpoint but they can nonetheless prove useful for computation performance in-depth cross-checking.

Here it was specifically important to use at least one such lower case digit, namely the one for the Longitude because when you round-off a value ending by 4, 5 , or 6 - with "4" being the case here - your absolute error is biggest then. This could become a problem when nit-picking numbers themselves. This is [much] less the case when you round off 0, 1, 2 or even 3 to "zero" and the same also holds true when rounding-off 9, 8, or even 7 to the immediately higher left digit.

With this rule in mind, I then could have skipped indicating the lower case digit for Latitude - namely a "1" here - but the non-symetrical display/layout between both coordinates then might possibly have raised doubts about a possible typo somewhere.

Does this reply make sense to you ?

Thanks for your kind inquiry and Best Regards,

Antoine M. Couëtte

What is NavList?

NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

NavList is more than an online community... more about that another day.
