CLAMP(3G)

💖 CLAMP(3G) 💖

okay so bestie, welcome to clamp from the 3G manual section — yeah the OpenGL shading language girlies ✨ she's literally the "keep it in range" function and she ATE 💅

---

🎀 NAME 🎀

clamp — constrain a value so it lies between two further values 🫶 like a little velvet rope for your numbers

---

✨ DECLARATION ✨

here's the whole friend group, no cap, all of them:

genType clamp(genType x, genType minVal, genType maxVal);

genType clamp(genType x, float minVal, float maxVal);

genDType clamp(genDType x, genDType minVal, genDType maxVal);

genDType clamp(genDType x, double minVal, double maxVal);

genIType clamp(genIType x, genIType minVal, genIType maxVal);

genIType clamp(genIType x, int minVal, int maxVal);

genUType clamp(genUType x, genUType minVal, genUType maxVal);

genUType clamp(genUType x, uint minVal, uint maxVal);

---

🌸 PARAMETERS 🌸

• x — the value you wanna constrain. the main character of this whole operation 👑
• minVal — the lower end of the range you're cramming x into. the floor, the basement, the "no lower than this" 🧚
• maxVal — the upper end of that same range. the ceiling bestie, the "no higher than this" ⭐

---

💅 DESCRIPTION 💅

so clamp hands you back the value of x, except it's been constrained to the range from minVal to maxVal. like, she will not let it out of the enclosure, periodt.

the returned value is computed as:

min()(max()(x, minVal), maxVal)

that's literally it. that's the whole vibe. the way that she's just min and max stacked on top of each other… iconic 🌈

bestie this is a table that got turned into a list, so read it like a table, not like a timeline of my feelings (it's both tho)
