al_fixatan(3alleg5)

✨ al_fixatan — Allegro 5 API ✨

okay bestie, pull up a chair 🎀 this one is al_fixatan(3alleg5) from the Allegro 5 API and it's genuinely so useful, no cap.

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

al_fixed al_fixatan(al_fixed x)

---

💜 DESCRIPTION 💜

so this function finds the inverse tangent of a value, and the way it does that is by using a lookup table 🫶 (yes, it's giving efficient, it's giving iconic).

the input has to be a fixed point value, okay? that's the vibe check here, don't come at it with anything else 💅

and just so we're clear: the inverse tangent is the value whose tangent is x. that's it, that's the whole thing, periodt.

Example:

al_fixed result;

/* Sets result to binary angle 13. */
result = al_fixatan(al_ftofix(0.326));

not me showing you the exact same example as the original because I would never change a single character of your code, iykyk 😭

---

⭐ RETURN VALUE ⭐

it returns the inverse tangent of a fixed point value, measured as a fixed point binary format angle 🌈 — so like, angle math but in fixed point form. slay.
