ATANH(3G)

✨ NAME ✨

atanh — bestie, this one hands you back the arc hyperbolic tangent of whatever parameter you toss at it 💖

(also hi, this is the 3G manual page, living in the OpenGL family, just so u know where u are 🫶)

---

🎀 DECLARATION 🎀

okay so here's the signature, literally copy it, don't freestyle:

genType atanh(genType x);

---

🌸 PARAMETERS 🌸

• x — the value whose arc hyperbolic tangent you want back. that's it. that's the whole job. she's simple, she's iconic 💅

---

💜 DESCRIPTION 💜

so atanh returns the arc hyperbolic tangent of x — she's the inverse of tanh(), the two of them are giving very much "you complete me" 😭

big warning bestie: the result is undefined if $\left| x \right| > 1$. like, undefined undefined. don't come crying to me when your shader starts acting haunted 💀

and that's the page, bestie 🫶 this was the ATANH(3G) manual, source listed as [FIXME: source] (yeah, still a FIXME, not me judging 🙈), dated 01/03/2018, and it literally signed off as ATANH(3G) one more time for the girls. slay, bye 💅
