💖 CSINH(3P) — the POSIX Programmer's Manual glow-up 💖

okay bestie, welcome to CSINH(3P) from the POSIX Programmer's Manual. we're doing complex hyperbolic sine today and honestly? she's iconic. let's get into it 💅

🌸 PROLOG 🌸

This manual page is part of the POSIX Programmer's Manual. Real talk though: the Linux implementation of this interface may differ (so go consult the corresponding Linux manual page for the deets on Linux behavior), or the interface might just... not be implemented on Linux at all. 🫠

✨ NAME ✨

csinh, csinhf, csinhl — complex hyperbolic sine functions. the trio. the girlies. 🎀

---

🦋 SYNOPSIS 🦋

#include <complex.h>

double complex csinh(double complex z);
float complex csinhf(float complex z);
long double complex csinhl(long double complex z);

---

💜 DESCRIPTION 💜

The functionality described on this reference page is aligned with the ISO C standard. And no cap — any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

These functions shall compute the complex hyperbolic sine of z. that's it, that's the whole job. 🧚

---

⭐ RETURN VALUE ⭐

These functions shall return the complex hyperbolic sine value. so slay, you get the answer back. 💖

ngl that's a lot of legal text but it's giving "we must protect the vibes (legally)". 💖

mwah 💋 that's the whole page bestie — brought to you by IEEE/The Open Group, 2017, and yes the footer really does say CSINH(3P) again like she's signing her own yearbook. go compute some hyperbolic sines, you main character. 🌸✨
