ROUND(3G)

🌸 ROUND(3G) 🌸

okay bestie, welcome to the ROUND(3G) manual page 💖 this is a [FIXME: manual] situation and we're gonna make it iconic anyway.

---

✨ NAME ✨

round — find the nearest integer less than or equal to the parameter 🎀

---

🦋 DECLARATION 🦋

here's the tea, the actual signatures, copied exactly, no notes:

genType round(genType x);

genDType round(genDType x);

---

🌈 PARAMETERS 🌈

• x — Specify the value to evaluate. that's it, that's the whole vibe, she's the one being evaluated 💅

---

👑 DESCRIPTION 👑

so round returns a value equal to the nearest integer to x. simple, slay.

but — and this is the part that lowkey matters — the fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is fastest 🔥. and that includes the possibility that round(x) returns the same value as roundEven()(x) for all values of x. so yeah, don't come for her about which way 0.5 goes, it's giving "implementation's choice" fr fr 😭

💀 VERSION SUPPORT 💀

okay so here's who's invited to the party, by OpenGL Shading Language Version 🫶
