order_base_2(9)

💖 NAME 💖

okay so bestie, this is the order_base_2 page from the Kernel API Manual, and the whole vibe is: calculate the (rounded up) base 2 order of the argument. no cap. 🫶

---

✨ SYNOPSIS ✨

order_base_2 (n );

---

🎀 ARGUMENTS 🎀

• n — parameter. that's literally the whole argument description. iconic minimalism. 💅

---

🦋 DESCRIPTION 🦋

the first few values calculated by this routine are, fr fr:

ob2(0) = 0 ob2(1) = 0 ob2(2) = 1 ob2(3) = 2 ob2(4) = 2 ob2(5) = 3 ... and so on.

so yeah — ob2(0) is 0, ob2(1) is 0, ob2(2) is 1, ob2(3) is 2, ob2(4) is 2, ob2(5) is 3, and it just keeps rolling from there. periodt. 🌈
