PDL::Constants(3pm)

💖 PDL::Constants — the manual page, but make it cute 💖

okay bestie, so this is PDL::Constants for the PDL crew — and it's literally just the basic compile time constants. the icons. the legends. the numbers you keep retyping. 🎀

---

✨ NAME ✨

PDL::Constants — basic compile time constants for PDL 🦋

---

🌸 DESCRIPTION 🌸

this module is here to define compile time constant values for PDL, no cap. and the way it does it?? it uses Perl's constant pragma, because honestly it's giving simplicity and availability. iconic behavior fr fr 💅

---

⭐ SYNOPSIS ⭐

use PDL::Constants qw(PI E);
print 'PI is ' . PI . "\n";
print 'E  is ' .  E . "\n";

see how easy that is?? qw(PI E) and you're done, main character energy only ✨

---

🥧 PI 🥧

the ratio of a circle's circumference to its diameter. yes, that ratio. the one your math teacher was obsessed with. π 🫶

---

📐 DEGRAD 📐

the number of degrees of arc per radian — that's 180/PI bestie. so if you got radians and you want degrees, this is your girl 💜

---

🔄 DEG2RAD 🔄

the constant that converts degrees of arc into radians — PI/180. look at the lil example:

$radians = DEG2RAD * $degrees;

multiply and slay 🔥

---

🔁 RAD2DEG 🔁

the constant that converts radians into degrees of arc — 180/PI. here's the vibe:

$degrees = RAD2DEG * $radians;

(yeah, DEGRAD and RAD2DEG are both 180/PI — not me noticing that 👀 — that's just how the module rolls, no cap.)

---

🧮 E 🧮

the base of the natural logarithms, aka Euler's number. the e. the moment. 💅

and that's the whole page!! this one was rendered with perl v5.42.3, dated 2026-08-20, and honestly?? a little math constants moment was exactly what the timeline needed. stay nerdy, stay iconic 🎀✨💖
