Hello All,
I just bought a 50g and cannot figure out how to input and return angles in DMS. I do this frequently and would like to have it readily available. Any suggestions?
Thank you very much,
Jeff

Read page 3-79 of the advanced users manual. ▼

The function ->HMS converts a decimal hour (or degree) into a form HH.MMSS and the function HMS-> converts HH.MMSS into a decimal value. As far as availability goes this function is found either in the CATALOG or in the TIME menu under tools. If you use it frequently consider making it a part of a CUSTOM menu or a user defined key.

Thank you very much for your replies. I have put the DMS commands on my Custom menu. How about entering and returning degrees, minutes, and seconds directly? I believe that you can on TIs by entering each value followed by a symbol (e.g. ' for minutes). I believe that results can be reported in a similar fashion. Any thoughts? Thanks again, Jeff ▼

Jeff, in RPL mode enter HH <space> MM <space> SS <Custom Function>. If your custom function has been built with (say as an example) DEFINE('K(h,m,s)=h*3600+m*60+s') in algebraic mode (which I suppose, because of your question), calling your custom function as described above will solve the RPL equation: << -> h m s 'h*3600+m*60+s' >> and display the expected result. For a description on DEFINE see Chapter 3 of the User Guide (the large pdf document on CD). For a more user-friendly implementation, pls. look up the fine descriptions of - '30 MENU' usage in equations - to build custom menus. A lot of sophisticated samples of this technique are available at http://groups.google.com/groups/search?q=30+menu&qt_s=Search+Groups Hope this helps! Peter A. Gebhardt |
