NAME

6       Geo::Functions - Package for standard Geo:: functions.
7

SYNOPSIS

9         use Geo::Functions qw{deg_rad deg_dms rad_deg}; #import into namespace
10         print "Degrees: ", deg_rad(3.14/4), "\n";
11
12         use Geo::Functions;
13         my $obj = Geo::Functions->new;
14         print "Degrees: ", $obj->deg_rad(3.14/2), "\n";
15

DESCRIPTION

CONVENTIONS

18       Function naming convention is "format of the return" underscore "format
19       of the parameters."  For example, you can read the deg_rad function as
20       "degrees given radians" or "degrees from radians".
21

CONSTRUCTOR
