MAX(3G)

✨ MAX(3G) — bestie edition ✨

okay so this is max, from section 3G of the manual (that's the OpenGL/GLSL corner of the world, iykyk 🎀). she's a tiny function with a big heart and she only has one job: pick the bigger number. that's it. that's the whole vibe. 💅

---

🌸 NAME 🌸

max — return the greater of two values

---

🦋 DECLARATION 🦋

here's every single way you can call her. all of these are real, don't skip any:

genType max(genType x, genType y);

genType max(genType x, float y);

genDType max(genDType x, genDType y);

genDType max(genDType x, double y);

genIType max(genIType x, genIType y);

genIType max(genIType x, int y);

genUType max(genUType x, genUType y);

genUType max(genUType x, uint y);

like yes she's flexible, she contains multitudes, main character energy fr fr 👑

---

💖 PARAMETERS 💖

• x — the first value you wanna compare. drop it in.
• y — the second value you wanna compare. drop it in too.

---

🌈 DESCRIPTION 🌈

so max returns the maximum of the two parameters. like, she looks at both of them and goes "okay which one of you is bigger".

and the actual rule, no cap: it returns y if y is greater than x, otherwise it returns x.

that's the whole thing. she ate and left no crumbs. ✨

👑 VERSION SUPPORT 👑

not every flavor of max showed up on day one, so here's the receipts for every OpenGL Shading Language version. (the original had this in a cute lil grid — we're doing it as lists because tables are not the vibe here 🫶)
