MODF(3G)

💖 MODF(3G) — the modf page, bestie edition 💖

okay so this is modf, and it lives in the 3G manual, which is the OpenGL Shading Language corner of the universe ✨ (the header calls the manual [FIXME: manual], iconic placeholder behaviour, we love her 🎀).

---

🌸 NAME 🌸

modf — separate a value into its integer and fractional components 💅

---

✨ DECLARATION ✨

bestie here is the actual signature, copy it exactly okay, no typos, no vibes-based guessing 🫶

genType modf(genType x, out genType i);

genDType modf(genDType x, out genDType i);

---

🎀 PARAMETERS 🎀

• x — this is the value you wanna separate, the poor little thing is getting split in half 😭
• out i — a variable that receives the integer part of the argument. note the out — she's an output, she's the one catching the integer half 🫴

---

💜 DESCRIPTION 💜

so modf takes a floating point value x and goes ✂️ and splits it into its integer part and its fractional part. the fractional part is what gets returned from the function (main character energy, she comes back out front), and the integer part (as a floating point quantity, ok, not an int, don't come for me) gets returned in the output parameter i. two halves, two delivery methods, one very efficient little function, we stan 🌈

👑 VERSION SUPPORT 👑

this is the whole vibe check of "which GLSL version will even let you use this", and the answer is: genType has been around longer than genDType. periodt 💅
