Geo::Constants(3pm)

Usage

  use Geo::Constants qw{PI DEG RAD}; #import into namespace
  print "PI:  ", PI(), "\n";
  print "d/r: ", DEG(), "\n";
  print "r/d: ", RAD(), "\n";
  use Geo::Constants;                #Perl OO
  my $obj = Geo::Constants->new();
  print "PI:  ", $obj->PI, "\n";
  print "d/r: ", $obj->DEG, "\n";
  print "r/d: ", $obj->RAD, "\n";

Functions

Pi

  my $pi = $obj->PI;
  use Geo::Constants qw{PI};
  my $pi = PI();

Deg

  my $degrees_per_radian = $obj->DEG;
  use Geo::Constants qw{DEG};
  my $degrees_per_radian = DEG();

UOM: degrees/radian

Rad

  my $radians_per_degree = $obj->RAD;
  use Geo::Constants qw{DEG};
  my $radians_per_degree = RAD();

UOM: radians/degree
