ROUNDEVEN(3G)

💖 roundEven — find the nearest even integer to the parameter 💖

okay bestie, this is roundEven(3G) — the section 3G of the manual, so it's a GLSL shading-language thing, not a command you run in your shell. no cap. 🎀

✨ NAME ✨

roundEven — find the nearest even integer to the parameter 👑

🌸 DECLARATION 🌸

here's the signature, exactly as written, don't touch a character:

genType roundEven(genType x);

genDType roundEven(genDType x);

🦋 PARAMETERS 🦋

• x — Specify the value to evaluate. that's the whole assignment, girl. hand it a value, it does the thing. 💅

💜 DESCRIPTION 💜

so roundEven returns a value equal to the nearest integer to x. but here's the twist that makes it the main character: the fractional part of 0.5 will round toward the nearest even integer. for example, both 3.5 and 4.5 will round to 4.0. yes literally both. that's not a typo, that's the entire point of the function. it's giving banker's rounding energy. ✨

🔥 VERSION SUPPORT 🔥

the original ships this as a big gorgeous grid of OpenGL Shading Language Versions, so let me unspool it for you cell by cell, no details lost. the versions we're checking 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. 🫶

🌈 roundEven (genType)

• 1.10 — - (nope, not yet)
• 1.20 — - (still nope)
• 1.30 — ✔
• 1.40 — ✔
• 1.50 — ✔
• 3.30 — ✔
• 4.00 — ✔
• 4.10 — ✔
• 4.20 — ✔
• 4.30 — ✔
• 4.40 — ✔
• 4.50 — ✔

💫 roundEven (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 the genType girlies got in at 1.30, and the genDType girlies had to wait all the way until 4.00. we love a late bloomer. 😭💖

okay that's the whole page, ate and left no crumbs, go forth and round to the nearest even integer fr fr 🎀💖
