  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.
