NAME

       Geo::Functions - Package for standard Geo:: functions.

SYNOPSIS

         use Geo::Functions qw{deg_rad deg_dms rad_deg}; #import into namespace
         print "Degrees: ", deg_rad(3.14/4), "\n";

         use Geo::Functions;
         my $obj = Geo::Functions->new;
         print "Degrees: ", $obj->deg_rad(3.14/2), "\n";

DESCRIPTION

CONVENTIONS

       Function naming convention is "format of the return" underscore "format of the parameters."  For example,
       you can read the deg_rad function as "degrees given radians" or "degrees from radians".

CONSTRUCTOR

   new
       The new() constructor

         my $obj = Geo::Functions->new();

METHODS

   deg_dms
       Degrees given degrees minutes seconds.

         my $deg=deg_dms(39, 29, 17.134);

         my $deg=deg_dms(39, 29, 17.134, 'N');

   deg_rad
       Degrees given radians.

         my $deg=deg_rad(3.14);

   rad_deg
       Radians given degrees.

         my $rad=rad_deg(90);

   rad_dms
       Radians given degrees minutes seconds.

         my $rad=rad_dms(45 30 20.0);

   round
       Round to the nearest integer. This formula rounds toward +/- infinity.

         my $int=round(42.2);

   dms_deg
       Degrees minutes seconds given degrees.

         my ($d, $m, $s, $sign)=dms_deg($degrees, qw{N S});
         my ($d, $m, $s, $sign)=dms_deg($degrees, qw{E W});

   dm_deg
       Degrees minutes given degrees.

         my ($d, $m, $sign)=dm_deg($degrees, qw{N S});
         my ($d, $m, $sign)=dm_deg($degrees, qw{E W});

   mps_knots
       meters per second given knots

         my $mps=mps_knots(50.0);

   knots_mps
       knots given meters per second

         my $knots=knots_mps(25.0);
