TRUNC(3G)

👑 TRUNC(3G) 👑

okay bestie, welcome to the TRUNC(3G) page — yes it's literally just about rounding down-ish, but she's an icon and we're gonna treat her with respect 💅

💖 NAME 💖

trunc — find the nearest integer less than or equal to the parameter

✨ DECLARATION ✨

genType trunc(genType x);

genDType trunc(genDType x);

🎀 PARAMETERS 🎀

• x — specify the value to evaluate. that's it, that's the whole input, hand her a number and she'll do her thing 🫶

🦋 DESCRIPTION 🦋

trunc returns a value equal to the nearest integer to x whose absolute value is not larger than the absolute value of x. no cap, that's the entire job description — she's chopping toward zero and she is not sorry about it 🌸

👑 VERSION SUPPORT 👑

so here's the vibe check on which OpenGL Shading Language Versions actually support her. the columns are 1.10, 1.20, 1.30, 1.40, 1.50, 3.30, 4.00, 4.10, 4.20, 4.30, 4.40, 4.50 — a - means nope, a ✔ means slay 🔥

• trunc (genType) — 1.10: -, 1.20: -, 1.30: ✔, 1.40: ✔, 1.50: ✔, 3.30: ✔, 4.00: ✔, 4.10: ✔, 4.20: ✔, 4.30: ✔, 4.40: ✔, 4.50: ✔
• trunc (genDType) — 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 genType showed up in 1.30 and never left, but genDType was a whole late bloomer — she didn't arrive until 4.00. we love a delayed glow-up 😭
