✨ LOG(3G) ✨

okay bestie, gather round 💖 this is the manual page for log, from section 3G of the manual (yes, the OpenGL shading language corner of the docs 🎀). It's giving "math but make it shader", and honestly? Iconic.

🌸 NAME 🌸

log — return the natural logarithm of the parameter 🧮✨

💅 DECLARATION 💅

genType log(genType x);

That's it. That's the whole signature. Simple, clean, main character energy fr fr 👑

🎀 PARAMETERS 🎀

  • x — the value you want to take the natural logarithm of. Hand it over and let log do its thing 💖

🦋 DESCRIPTION 🦋

So log returns the natural logarithm of x, which means it gives you back the value y that satisfies:

x = e^y
⚠️ okay so important: the result is undefined if x ≤ 0. Not "weird", not "surprising" — undefined. So don't be out here logging zero or negative numbers and then acting shocked when things go sideways 😭💀

🌈 VERSION SUPPORT 🌈

Bestie here's the vibe check: this function is supported in every version of the OpenGL Shading Language listed. Every. Single. One. No cap 🔥

The table in the original tracks two column groups: Function Name and OpenGL Shading Language Version. And the row is log (genType). Here's the receipts ✨:

  • 1.10 — ✔
  • 1.20 — ✔
  • 1.30 — ✔
  • 1.40 — ✔

and that's the whole page, bestie 🫶 source says [FIXME: source] (yeah, they left it as a FIXME, we love that for them 🙈) and the date on this one is 01/03/2018. LOG(3G) forever, mwah 💋✨
