ATANF(3P)

💖 PROLOG 💖

okay bestie, real talk before we even get into it: this manual page is part of the POSIX Programmer's Manual. that's the vibe. but heads up, the Linux implementation of this interface may differ, so if you're on Linux, go check the corresponding Linux manual page for the actual deets. and lowkey, the interface might not even be implemented on Linux at all. it's giving "consult your local manpage" energy. 🫶

✨ NAME ✨

atanf — arc tangent function 🎀

🌸 SYNOPSIS 🌸

#include <math.h>

float atanf(float x);

periodt. that's the whole signature. no notes. 👑

💅 DESCRIPTION 💅

okay so, for the actual description? refer to atan(). that's it, that's the tea. this one's just the float girlie of the family, and atan() has the full lore. iykyk. ✨
