uatof(3alleg4)

✨ uatof ✨

okay bestie, so this is a page from the Allegro manual — aka the Allegro game programming library 💖 — and today's main character is uatof, a lil function that takes a string and turns it into a double. it's giving "glow up for text" fr fr 🦋

🌸 SYNOPSIS 🌸

#include <allegro.h>

double uatof(const char *s);

like yes, that's the whole thing. two lines. she's simple, she's iconic, she eats 💅

🎀 DESCRIPTION 🎀

so what she does is: take as much of the string as she possibly can and convert it into an equivalent double precision real number. not all of it if it can't — as much as possible, no cap ✨

and the way that she's literally almost exactly like ustrtod(s, NULL)? yeah. that's the vibe. if you know ustrtod you already know her, iykyk 🤝

💖 RETURN VALUE 💖

she hands you back the equivalent value 🫶

but if the string doesn't actually represent a number? you get zero. that's it. that's the whole mood. zero. 😭
