DISTANCE(3G)

💖 distance — the 3G manual page, but make it cute 💖

okay so bestie, this is a page from the 3G manual, and it's all about one lil function called distance. she's simple, she's iconic, she measures how far apart two points are. that's it. that's the whole vibe. let's get into it 🦋

---

✨ NAME ✨

distance — calculate the distance between two points 🌸

like. literally that. the girl math is mathing.

---

✨ DECLARATION ✨

here's how you summon her, no cap, copy these exactly:

float distance(genType p0, genType p1);

double distance(genDType p0, genDType p1);

two flavors: the float one takes genTypes, the double one takes genDTypes. pick your fighter 💅

---

✨ PARAMETERS ✨

• p0 — the first of the two points 🫶
• p1 — the second of the two points 🫶

that's the whole guest list. two points. main characters only.

---

✨ DESCRIPTION ✨

so distance returns the distance between the two points p0 and p1. i.e.,

length(p0, p1);

and that's the tea ☕ she's just handing you the distance. no drama, no side quests. slay 💜

✨ VERSION SUPPORT ✨

ngl this is the part where the shading language version girlies get picky. here's who's invited to the party 👑

• distance (genType) — supported in every single version listed: 1.10, 1.20, 1.30, 1.40, 1.50, 3.30, 4.00, 4.10, 4.20, 4.30, 4.40, 4.50. all ✔, all the way down. she's been here since day one and she's not leaving 🔥
• distance (genDType) — not supported in 1.10, 1.20, 1.30, 1.40, 1.50, or 3.30 (those are all -, so don't come crying to her). she shows up starting at 4.00 and is supported in 4.00, 4.10, 4.20, 4.30, 4.40, and 4.50. ✔ from 4.00 onward, periodt.

bestie if you're on anything below 4.00 and you're reaching for the genDType version… she is simply not there. the - is not a vibe, it's a boundary 💀
