pub fn float_dense_body_f64_simd<const LANES: usize>(
op: ArithmeticOperator,
lhs: &[f64],
rhs: &[f64],
out: &mut [f64],
)Expand description
SIMD f64 arithmetic kernel for dense arrays (no nulls). Vectorised operations with scalar fallback for power operations and array tails. Division by zero produces Inf/NaN following IEEE 754 semantics.
