  Are you using some sort of routing software, or is it strictly "as the crow flies" from where you are to the destination?  In many areas, the difference in ETA can be extreme.

      Worked it out 

      $dist = sprintf("%06.2f",$dist);
      $bearing = sprintf("%06.2f",$bearing);

      3 leading - zero padded , 2 trailing

        Wonder is someone can help

        I want to format a number in perl 

        3 leading 0 padded 
        2 trailing decimal places

        Do I have to treat to the left of the decimal point and to the right as two seperates ?

        I want 3.4565443 to look like "003.456"

        Working on some GPS code

        Using sprintf 

        This puts 3 leading and zero pads:-

        $dist = sprintf("%3d",$dist);
        $bearing = sprintf("%3d",$bearing);

        This puts two trailing :-

        print "RNG = ".sprintf("%.2f",$dist)."\n";
        print "BRG = ".sprintf("%.2f",$bearing)."\n";

        How do i put them together ?

          Hello

          I have an idea, although not new, but novel

          I am taking a small netbook and LINUX and a GPS.

          I now have the flexibility to do anything with it.

          I can program and make the netbook do what ever I want.

          One thing I am playing with is the perl Geo::Ellispoid module.

          This allows me to get range and bearing, and also I am working on ETA code as well.
