exfixed(3)

💖 exfixed 💖

okay bestie, welcome to the Allegro manual, page exfixed from section 3 — yes it's a library function page, and yes it's literally about fixed point maths. stay with me, it's giving math but make it cute 🧚✨

✨ NAME ✨

exfixed — using fixed point maths, bestie. it's an Allegro game programming library thing. 🎀

🌸 SYNOPSIS 🌸

#include <allegro.h>

Example exfixed

like. that's it. that's the whole vibe. #include <allegro.h> and then you just... run the example exfixed. iconic behavior honestly 💅

🦋 DESCRIPTION 🦋

so this program is a demonstration of how to use fixed point numbers, and no bc same, I also had to sit down for this one. here's the tea:

a fixed point number is a signed 32-bit integer</> that stores:

• the integer part in the upper 16 bits
• the decimal part in the 16 lower bits

that's it. that's the whole structure. 16 and 16, split right down the middle like a friendship bracelet 🫶

this example also does something a lil unusual: it talks to the user exclusively via the allegro_message() function. no fancy windows, no buttons, no nothing — just allegro_message() carrying the entire conversation. main character energy fr fr 😭

👑 SEE ALSO 👑

go read these next, bestie, they're all in the same friend group:

• END_OF_MAIN(3)
• allegro_init(3)
• allegro_message(3)
• fixdiv(3)
• fixed(3)
• fixmul(3)
• fixsqrt(3)
• fixtof(3)
• ftofix(3)
• itofix(3)

and that's the page!! this was Allegro, version 4.4.3, and we were reading exfixed(3) the whole time — so like, go forth and divide your 32-bit integers responsibly. no cap. slay 💖✨🎀
