🌸 CTANL — it's giving complex tangent, bestie 🌸

okay so this is a page from the POSIX Programmer's Manual (yes, the 3POSIX girlies know 💅), and we're talking about ctanl, the long-double-complex-tangent of the family. buckle up, it's short but iconic.

✨ PROLOG ✨

so like, this manual page is part of the POSIX Programmer's Manual, periodt.

bestie, real talk: the Linux implementation of this interface may differ. so consult the corresponding Linux manual page for details of Linux behavior. OR — plot twist 😭 — the interface may not be implemented on Linux at all. vibe check your system first, fr fr.

👑 NAME 👑

ctanl — complex tangent functions 🦋

---

🎀 SYNOPSIS 🎀

the way you literally just:

#include <complex.h>

long double complex ctanl(long double complex z);

and that's it. that's the whole thing. she's lowkey simple like that ✨

💖 DESCRIPTION 💖

refer to ctan().

...yeah. that's the whole description. no notes. the ctan() girlies have the full lore, this one is just her long double complex sister 🫶 go read that one, iykyk.
