Function sin8

src/platforms/trig8.h:51–54

8-bit wrappers derived from 16-bit LUTs. sin16 returns i16 [-32768..32767], offset to u16 [0..65535], then use int_scale for proper u16→u8 downscale (bit-replication rounding, not naive truncation).

// then use int_scale for proper u16→u8 downscale (bit-replication
// rounding, not naive truncation).
inline u8 sin8(u8 theta) FL_NOEXCEPT {
	u16 unsigned_result = static_cast<u16>(sin16(static_cast<u16>(theta) << 8)) + 32768;
	return fl::int_scale<u16, u8>(unsigned_result);
}

inline u8 cos8(u8 theta) { return sin8(theta + 64); }
