fixtof(3)

✨ fixtof ✨

okay bestie, welcome to the Allegro manual 🎀 and specifically to fixtof(3), a lil function from the Allegro game programming library that is, and I mean this, lowkey carrying your whole fixed-point-to-float pipeline. 💅

🌸 NAME 🌸

fixtof — converts a fixed point to floating point. Part of the Allegro game programming library, obviously. 👑

✨ SYNOPSIS ✨

#include <allegro.h>

double fixtof(fixed x);

like… that's it. one arg. one return value. no drama. 🫶

💖 DESCRIPTION 💖

So here's the vibe: fixtof takes a fixed point value and converts it to floating point. That's the whole job. It does it. It slays. ✨

And because a demo is worth a thousand words, here's the example straight from the source, no cap:

float result;

/* This will put 33.33333 into `result'. */
result = fixtof(itofix(100) / 3);
/* This will put 16.66666 into `result'. */
result = fixtof(itofix(100) / 6);

see how it's giving math? itofix(100) goes in as fixed, fixtof brings it back out as a float, and the division just… works. iconic behaviour fr fr. 🌈
