✨ exfixed ✨

okay so bestie, welcome to exfixed from the Allegro manual — it's a lil example page (yes, from the Allegro game programming library, we're being fancy today 💅) and it's all about fixed point maths. no cap, it's shorter than your attention span, so let's go 🦋

🎀 SYNOPSIS 🎀

#include <allegro.h>

Example exfixed

literally just include the header and you're in, bestie. that's the whole vibe. ✨

💖 DESCRIPTION 💖

okay so this program is a whole demo of how to use fixed point numbers, and the way it works is genuinely iconic:

• they're signed 32-bit integers 🔥
• the integer part lives in the upper 16 bits 👑
• the decimal part lives in the 16 lower bits 💅

that's it. that's the whole thing. 32 bits, split down the middle, half whole numbers half decimals, main character energy fr fr.

and then — not me being obsessed with this — the example also does the unusual approach of talking to the user exclusively through the allegro_message() function. like, no window, no console, just vibes and message boxes. iykyk. 🫶

ngl bestie, if you were expecting a whole graphical showcase, this is not that. it's a message-box-only situation. that's the point of the example, okay?? 😭

and that's the whole page!! 🎀 this one came from Allegro, version 4.4.3 — so when you cite it, cite it right. stay slay, go write some fixed point maths, and remember: upper 16 bits, lower 16 bits, allegro_message(), periodt. 💖✨🦋
