Thanks! That's cool to know. I did my error calculations by brute forcing the whole 16-bit range, basically: for i in (i16::MIN..=i16::MAX) { let a = (i as f32).sin() as i16; let b = lut_sin(i); let diff = abs_diff(a, b); } Which found the largest difference to be 4, and I got 0.012% from (4/32768).
