ISINF(3G)

💖 ISINF(3G) — the isinf page, bestie edition 💖

okay so real talk: this is ISINF(3G) from the manual, and it's giving "tiny function, huge main character energy." let's get into it ✨

---

🌸 NAME 🌸

isinf — figure out whether the parameter is positive or negative infinity 🦋

---

✨ DECLARATION ✨

genBType isinf(genType x);

genBType isinf(genDType x);

---

🎀 PARAMETERS 🎀

• x — the value you want to test for infinity. that's it, that's the whole job 💅

---

💜 DESCRIPTION 💜

so for each element i of the result, isinf returns true if x[i] is positive or negative floating point infinity, and false otherwise. periodt. 💖

ngl it's not out here telling you which infinity you got — positive or negative, both count, it just says "yep that's infinite bestie" 😌

👑 VERSION SUPPORT 👑

the whole OpenGL Shading Language version situation, laid out cute because we don't do tables here:

isinf (genType) — slayed in every single version:

• 1.10 ✔
• 1.20 ✔
• 1.30 ✔
• 1.40 ✔
• 1.50 ✔
• 3.30 ✔
• 4.00 ✔
• 4.10 ✔
• 4.20 ✔
• 4.30 ✔
• 4.40 ✔
• 4.50 ✔

isinf (genDType) — late bloomer era 😭, showed up at 4.00:

• 1.10 -
• 1.20 -
• 1.30 -
• 1.40 -
• 1.50 -
• 3.30 -
• 4.00 ✔
• 4.10 ✔
• 4.20 ✔
• 4.30 ✔
• 4.40 ✔
• 4.50 ✔

so like, if you're on genDType and you're living in anything before 4.00? not supported, bestie, it's giving nothing 🙈
