fixatan(3alleg4)

✨ NAME ✨

fixatan — the fixed point inverse tangent lookup table, bestie 💖 and it lives in the Allegro game programming library, iykyk.

🌸 SYNOPSIS 🌸

#include <allegro.h>

fixed fixatan(fixed x);

🎀 DESCRIPTION 🎀

Okay so. fixatan finds the inverse tangent of a value, and it does it with a lookup table — no cap, it's just chillin' there precomputed so you don't gotta do the math yourself. 🦋

The input value must be a fixed point radian. The inverse tangent is the value whose tangent is x. Periodt.

Example time, and it's giving iconic:

fixed result;

/* Sets `result' to binary angle 13. */
result = fixatan(ftofix(0.326));

💅 RETURN VALUE 💅

Returns the inverse tangent of a fixed point value, measured as a fixed point binary format angle. That's the whole vibe. ✨
