#[target_feature(enable = "avx512f")]
pub fn _mm_scalef_round_sd(a: __m128d, b: __m128d, ROUNDING: i32) -> __m128d

Scale the packed double-precision (64-bit) floating-point elements in a using values from b, store the result in the lower element of dst, and copy the upper element from a to the upper element of dst.\

Rounding is done according to the rounding[3:0] parameter, which can be one of:\
