💖 CSIN(3P) — POSIX Programmer's Manual 💖

okay bestie, welcome to the CSIN(3P) page, part of the POSIX Programmer's Manual ✨ buckle up, it's short but it's iconic

🌸 PROLOG 🌸

okay so first things first, real talk: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so like, go consult the corresponding Linux manual page for details on Linux behavior), or honestly the interface may not even be implemented on Linux at all. 💀 just a heads up, no cap.

👑 NAME 👑

csin, csinf, csinl — complex sine functions 🦋

---

✨ SYNOPSIS ✨

#include <complex.h>

double complex csin(double complex z);
float complex csinf(float complex z);
long double complex csinl(long double complex z);

---

💅 DESCRIPTION 💅

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional — fr fr, not on purpose. This volume of POSIX.1‐2017 defers to the ISO C standard.

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

---

🎀 RETURN VALUE 🎀

These functions shall return the complex sine value. periodt. 🌟
