ALLEGRO_PI(3alleg5)

✨ ALLEGRO_PI ✨

okay bestie, gather round, we're talking about π 💖

this is the page for ALLEGRO_PI, straight outta the Allegro 5 API. it's giving "tiny header, huge vibes", and honestly? iconic. 🎀

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

#define ALLEGRO_PI        3.14159265358979323846

like. look at that number. 3.14159265358979323846. she's so precise, she's so committed, she did NOT skip leg day. 💅

🦋 DESCRIPTION 🦋

so here's the tea, bestie: C99 compilers literally do not ship a predefined value like M_PI for the constant π. nope. not a thing. the compiler said "figure it out yourself" and walked away. 💀

but don't even worry about it, because you can use this one instead. that's it. that's the whole thing. one #define, one dream, one little circle constant ready to be radius-times-two'd. 🫶

lowkey the most useful one-liner in the whole header. no cap. 🌈

ngl, if you were out here typing M_PI and wondering why your build is mad at you — yeah, that's the plot twist. ALLEGRO_PI is your girl. 👑

and that's the page, bestie!! this lil masterpiece lives in the Allegro reference manual, page ALLEGRO_PI(3alleg5), and if anyone asks, you heard it here first. stay irrational, stay cute, and go calculate a circumference. 🍓✨💜
