AuFixedPointRoundUp(3)

💖 AuFixedPointRoundUp(3) — like, the manual page bestie 💖

okay so welcome to the audiolib cinematic universe, where the star of today's episode is AuFixedPointRoundUp from section 3 of the manual. she rounds things UP. that's her whole thing. she's an icon, she's a macro, she's lowkey doing the most with the least. let's get into it 🫶

✨ Name ✨

AuFixedPointRoundUp — and yes bestie, that trailing dash in the original is just the manpage being mysterious, there's no tagline, she simply IS. 💅

🎀 Synopsis 🎀

first you gotta pull her in from the header, no cap:

#include <audio/audiolib.h>

then you call her like this:

AuFixedPointRoundUp(fp)
      AuFixedPoint fp;

that's it. that's the whole vibe. 🌸

🦋 Arguments 🦋

  • fp — the fixed point value in question. like, the actual number you're handing over so she can do her lil round-up moment. she needs it, you give it, everybody's happy. ✨

💜 Description 💜

AuFixedPointRoundUp returns the rounded up integral portion of fp. that's the tea. you give her a fixed point value, she gives you back the integer-y part, but rounded up instead of just chopped. round up, not round down, not round-toward-zero, UP. periodt. 👑

and here's the juicy bit that iykyk: AuFixedPointRoundUp is implemented as a macro. so she's not some fancy function doing a whole function-call situation, she's a macro, she's fast, she's efficient, she's giving main character energy with zero overhead. don't be weird about it in a debugger, just accept her for who she is. 💀
