⚠️ but real talk — the Linux implementation of this interface may differ. like, the vibes could be off. so if you're on Linux, go consult the corresponding Linux manual page for the deets on Linux behavior. orrrr... plot twist: the interface might not even be implemented on Linux at all. no cap. so check first, bestie. 🫶

🌸 NAME 🌸

casinl — complex arc sine functions 🦋

(that's the whole name section. she said "complex arc sine functions" and dipped. main character energy honestly.)

---

✨ SYNOPSIS ✨

here's the tea, literally copy-paste this energy:

#include <complex.h>

long double complex casinl(long double complex z);

so you pull in <complex.h>, and then casinl takes one long double complex called z and hands you back a long double complex. that's the whole deal, periodt. 💜

💫 DESCRIPTION 💫

ngl this section is giving "girl, go look at the other page" energy:

Refer to casin().

that's it. that's the description. she's pointing you at her sibling. go read casin(), bestie, it's got the lore. 🙈
