COSL(3P)

💖 COSL(3P) — the POSIX Programmer's Manual, bestie edition 💖

okay so you found cosl, the long double cosine function, living its best life in the POSIX Programmer's Manual. Pull up a chair, we're gonna get you all the way caught up. ✨

🌸 PROLOG 🌸

Real talk first, bestie: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the deets on Linux behavior. Or, plot twist, the interface might not even be implemented on Linux at all. 🙈 Check before you commit, fr fr.

🎀 NAME 🎀

cosl — the cosine function 💅

✨ SYNOPSIS ✨

#include <math.h>

long double cosl(long double x);

Look at her. Clean. Iconic. Long double in, long double out. 👑

🦋 DESCRIPTION 🦋

ngl, this page is short on purpose: refer to cos(). That's it, that's the whole description. cosl is the long double flavor of the same vibe, and the main character cos() page has the full lore. iykyk. 💜
