CTANH(3POSIX)

🌸 PROLOG 🌸

okay bestie, real talk before we get into it 💖 this manual page is part of the POSIX Programmer's Manual. the Linux implementation of this interface may differ — so if you're on Linux, go peek at the corresponding Linux manual page for the actual deets on Linux behavior. also possible: the interface just straight-up isn't implemented on Linux at all 🙈. vibe check accordingly.

✨ NAME ✨

ctanh, ctanhf, ctanhl — the complex hyperbolic tangent functions, aka the hyperbolic tangent but make it complex 🦋

---

🎀 SYNOPSIS 🎀

#include <complex.h>

double complex ctanh(double complex z);
float complex ctanhf(float complex z);
long double complex ctanhl(long double complex z);

---

💅 DESCRIPTION 💅

okay so, the functionality described on this reference page is aligned with the ISO C standard. and like, if there's any conflict between what's written here and the ISO C standard? that was not intentional bestie, it's giving clerical error. this volume of POSIX.1‐2017 defers to the ISO C standard, periodt. the ISO C standard is the main character here 👑.

these functions shall compute the complex hyperbolic tangent of z. that's it, that's the whole job. iconic behavior honestly 🫶

---

🔥 RETURN VALUE 🔥

these functions shall return the complex hyperbolic tangent value. simple as that, no plot twist 💖

---

💀 ERRORS 💀

no errors are defined. zero. none. not a single one. we are blessed 🙏✨

the following sections are informative.

---

🌈 EXAMPLES 🌈

none. (i know, i know — no examples, tragic, but that's what it says 😭)

---

🍓 APPLICATION USAGE 🍓

none. nothing to report, bestie 🎀

---

🧚 RATIONALE 🧚

none. the reasoning is a mystery, a vibe, a secret 💜

---

⭐ FUTURE DIRECTIONS ⭐

none. the future is... unchanged. lowkey peaceful ngl 🦋

that's a wrap on CTANH(3POSIX), brought to you by IEEE/The Open Group, 2017 ✨ mwah, go compute some complex hyperbolic tangents, you gorgeous nerd 💅💖
