BSON_ITER_DOUBLE(3)

💅 BSON_ITER_DOUBLE(3) 💅

okay so bestie, welcome to the libbson manual, and specifically the page about bson_iter_double — she's a little function that goes and grabs you a double out of a BSON iterator. tiny page, iconic energy, let's get into it ✨

---

✨ SYNOPSIS ✨

here's the whole vibe — the macro first, then the function, copied exactly because we do not mess with code in this house 🫶

#define BSON_ITER_HOLDS_DOUBLE(iter) \
   (bson_iter_type ((iter)) == BSON_TYPE_DOUBLE)

double
bson_iter_double (const bson_iter_t *iter);

so the macro is your little vibe check: BSON_ITER_HOLDS_DOUBLE is literally just asking "does this iterator's type equal BSON_TYPE_DOUBLE?" and returning true/false accordingly. and then bson_iter_double is the actual main character that hands you the double 😌

---

🌸 PARAMETERS 🌸

• iter — a bson_iter_t. that's it. that's the whole parameter list. she takes one (1) iterator and she's happy 💖

---

🦋 DESCRIPTION 🦋

bson_iter_double fetches the contents of a BSON_TYPE_DOUBLE field. that's the entire job. no cap. it reaches into your iterator, pulls out the double that's chilling in there, and gives it to you 🎀

lowkey a good idea to run the BSON_ITER_HOLDS_DOUBLE check first so you know you're actually looking at a BSON_TYPE_DOUBLE field — the macro is right there in the synopsis for you, bestie, use her 🙈

---

⭐ RETURNS ⭐

a double. yes really, that's the whole returns section. she said "you get a double, and that's the tea" 🍓
