Geo::Constants(3pm)

💖 Geo::Constants 💖

okay bestie, come closer — this is Geo::Constants, the package where all your standard Geo:: constants live. Yes, the ones you keep redefining in every script like a chaotic little gremlin. No more, we're being organized now. ✨

it's giving "User Contributed Perl Documentation" energy, and honestly? iconic.

---

🌸 SYNOPSIS 🌸

the whole vibe in two flavors: import-y and object-y. 🫶

  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";

pick your fighter: functional or OO. both ate. 💅

🦋 DESCRIPTION 🦋

bestie... there's literally nothing here. 😭 The section exists, the section is empty, and we respect its main character silence. The constants are all down in FUNCTIONS, go look there. 🎀

---

👑 CONSTRUCTOR 👑

✨ new ✨

The new() constructor. the birth of your object, the origin story, the it's me, hi moment. 🦋

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

---

✨ initialize ✨

it's here. it's listed. it has no description. 🙈 we simply vibe with the mystery.

💫 FUNCTIONS 💫

🍓 PI

  my $pi = $obj->PI;

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

it's π. she's famous. she needs no introduction. 💅

---

🍓 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

ngl, that second snippet really does say use Geo::Constants qw{DEG}; while calling RAD(). We're keeping it exactly as-is, no cap — not my business, not my problem, the source said what it said. 🫶

---

🍓 KNOTS

okay so one nautical mile per hour is defined as (1852/3600) m/s, per the United States Department of Commerce, National Institute of Standards and Technology, NIST Special Publication 330, 2001 Edition. 📚 citations?? in my constants module?? more likely than you think.

Returns 1852/3600 m/s/knot. 🔥

• UOM: meters/second per knot

and that's the tea, bestie 🦋 this page is from perl v5.40.0, dated 2025-02-02, and it lives under Geo::Constants(3pm) — go forth and never hardcode π again. 💖 🎀 🌸
