CATANL(3POSIX)

💖 CATANL — it's giving "complex arc tangent" 💖

okay bestie, welcome to the POSIX Programmer's Manual, page CATANL(3POSIX), section 3POSIX 🎀 — yes we're doing the 3 section today, math-girlie edition, and it's lowkey iconic.

🌸 PROLOG 🌸

so like, real talk first: this manual page is part of the POSIX Programmer's Manual. 🫶

Heads up bestie: the Linux implementation of this interface may differ (so pls consult the corresponding Linux manual page for the details of Linux behavior), or the interface might not even be implemented on Linux at all. 💀 no cap.

✨ NAME ✨

catanl — the complex arc tangent functions 🌈 (yes, complex, as in complex numbers, she's a math baddie)

🦋 SYNOPSIS 🦋

#include <complex.h>

long double complex catanl(long double complex z);

look at her. so simple. so clean. long double complex in, long double complex out. main character energy fr fr. 👑

💅 DESCRIPTION 💅

okay so, the way this works is: you just refer to catan(). that's it. that's the whole description. she's not gonna repeat herself, periodt. 💅✨
