avivo_reduce_ratio(9)

💅 avivo_reduce_ratio 💅

okay so this is avivo_reduce_ratio(9) from the Kernel API Manual, and honestly? she's a little math baddie and we're obsessed 🎀

---

✨ NAME ✨

avivo_reduce_ratio — fractional number reduction, aka making your fraction live its best simplified life 💖

---

🦋 SYNOPSIS 🦋

void avivo_reduce_ratio (unsigned *nom , unsigned *den , unsigned
       nom_min , unsigned den_min );

like literally that's the whole vibe. four params, no return, no drama ✨

---

🌸 ARGUMENTS 🌸

• nom — the nominator 🫶 (yes bestie, nominator, that's what the page says, we do not correct the manpage, we respect the manpage)
• den — the denominator, her other half 💜
• nom_min — the minimum value for the nominator, aka the floor she refuses to go below ⭐
• den_min — the minimum value for the denominator, same energy, different variable 🌈

---

🔥 DESCRIPTION 🔥

okay so picture this: you have a fraction, right? and it's giving unsimplified. 😭

So what this does is it finds the greatest common divisor and applies it to both the nominator and the denominator — divide them both, slay, reduce, periodt 💅 — BUT (and this is the main character plot twist) it makes sure the nominator and denominator are at least as large as their minimum values 🫶

so like. reduce, yes. but never below nom_min and den_min. the minimums are the boundary and she respects the boundary, no cap 🔥
