fixfloor(3alleg4)

✨ fixfloor(3alleg4) ✨

okay bestie, welcome to the Allegro manual 💖 this one's a tiny lil function page and honestly? it's giving "short but essential". let's go 🎀

🌸 NAME 🌸

fixfloor — returns the greatest integer not greater than x. from the Allegro game programming library, no cap 👑

🦋 SYNOPSIS 🦋

#include <allegro.h>

int fixfloor(fixed x);

💅 DESCRIPTION 💅

so basically fixfloor hands you back the greatest integer that is not greater than x. that's the whole vibe. lowkey what it actually means is: it rounds towards negative infinity 🫶 like, always down, always toward the void, never toward zero. periodt.

here's the example, bestie, look at it:

int result;
/* This will put 33 into `result'. */
result = fixfloor(itofix(100) / 3);
/* And this will round down to 16. */
result = fixfloor(itofix(100) / 6);

see how itofix(100) / 3 slides a clean 33 into result? iconic. and itofix(100) / 6? that one rounds down to 16. the way it just... floors it 😭✨

heads up: this is fixed-point math, not float math — the fixed type and itofix are the Allegro way of doing decimals without decimals. iykyk 💀

and that's the whole page, babes 🦋 this was pulled straight from Allegro version 4.4.3, dated with love, and it lives under the name fixfloor(3alleg4). go floor something. slay 💅💖
