✨ fixceil(3) ✨

okay bestie, welcome to the Allegro manual, the game programming library that literally raised so many of us 💖 this one's a tiny little math baddie and she is iconic

🎀 NAME 🎀

fixceil — returns the smallest integer not less than x. no cap, that's the whole job. from the Allegro game programming library, obvi 💅

🦋 SYNOPSIS 🦋

#include <allegro.h>

int fixceil(fixed x);

like, that's it. one include, one function, zero drama ✨

🌸 DESCRIPTION 🌸

so fixceil gives you the smallest integer that is not less than x. which is just a fancy way of saying it rounds towards positive infinity ⬆️⬆️⬆️ it never goes down, she only goes up, main character energy fr fr 👑

here's the example, and yes you should absolutely read it because it's giving chef's kiss:

int result;
/* This will put 34 into `result'. */
result = fixceil(itofix(100) / 3);
/* This will round up to 17. */
result = fixceil(itofix(100) / 6);

see how itofix(100) / 3 lands you on 34 in result? 🍓 and then dividing by 6 instead rounds up to 17? it's the same function just doing her little upward thing, obsessed honestly 😭💜

lowkey reminder bestie: it rounds toward positive infinity, not toward zero, not to nearest. up only. periodt.
