al_fixatan(3)

💅 NAME 💅

Okay so we're in the Library Functions Manual, and the main character is al_fixatan — a certified Allegro 5 API function, no cap. ✨

---

🌸 SYNOPSIS 🌸

Here's the little summoning circle, bestie — copy it exactly:

#include <allegro5/allegro.h>

al_fixed al_fixatan(al_fixed x)

---

🦋 DESCRIPTION 🦋

Okay so al_fixatan finds the inverse tangent of a value using a lookup table. The inverse tangent is literally the value whose tangent is x — that's the definition, iykyk. 🎀

Bestie, the input must be a fixed point value. That's the rule. 💀

Example moment:

al_fixed result;

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

---

👑 RETURN VALUE 👑

It returns the inverse tangent of a fixed point value, measured as a fixed point binary format angle. Slay. 💅
