find_closest_descending(9)

💅 NAME

okay so bestie, welcome to the Kernel API Manual entry for find_closest_descending(9) — it’s literally here to locate the closest element in a sorted array. slay.

✨ SYNOPSIS

find_closest_descending (x , a , as );

🎀 ARGUMENTS

• x — the reference value. like, the number you’re checking closeness against, bestie.
• a — the array where you look for the closest element. Must be sorted in descending order — no cap, that part matters.
• as — size of a. that’s the whole vibe.

🦋 DESCRIPTION

So it’s similar to find_closest, but plot twist: a is expected to be sorted in descending order. The iteration is done in reverse order, so that the comparison of __fc_right & __fc_left also works for unsigned numbers. that reverse-order moment is doing the real work here, fr fr 💅
