🌸 NAME 🌸

__fixp_sin32 — returns the sin of an angle in degrees 🦋

like… it's a sine function. for the kernel. that's the whole vibe. obsessed.

🎀 SYNOPSIS 🎀

s32 __fixp_sin32 (int degrees );

that's it. that's the whole signature. so clean, so iconic 💅

⭐ ARGUMENTS ⭐

• degrees — the angle, in degrees, from 0 to 360. literally just a good old angle, nothing spooky, promise 🫶

🌈 DESCRIPTION 🌈

👑 SEE ALSO 👑

peep the kernel file ./include/linux/fixp-arith.h for the whole friend group:

• fixp_sin32(9)
• fixp_sin32_rad(9)
• fixp_linear_interpolate(9)

they're all literally right there in the same header, go say hi 🧚
