  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.
