🎀 DIV64_U64_ROUND_CLOSEST(9) 🎀

okay so bestie, welcome to the Kernel API Manual page for DIV64_U64_ROUND_CLOSEST — manual name folded in near the top, as promised, not copied as a header line. This is the unsigned 64bit divide-with-nearest-integer entry, and it's giving main character energy in math64.h. 💅✨

✨ SYNOPSIS ✨

DIV64_U64_ROUND_CLOSEST (dividend , divisor );

🌸 ARGUMENTS 🌸

• dividend — the unsigned 64bit dividend, aka the number getting divided. 🫶
• divisor — the unsigned 64bit divisor, aka the number doing the dividing. 💖

🦋 DESCRIPTION 🦋

The actual move: divide the unsigned 64bit dividend by the unsigned 64bit divisor, then round to the closest integer. That's the whole vibe. Not extra, not mysterious — rounded to nearest integer, periodt. ✨

👑 RETURN 👑

It returns dividend / divisor rounded to the nearest integer. Slay. 💖🔥
