Function core::arch::x86_64::_mm_mask_rcp14_pd

pub unsafe fn _mm_mask_rcp14_pd(src: __m128d, k: __mmask8, a: __m128d) -> __m128d

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512f,avx512vl and x86-64 only.

Compute the approximate reciprocal of packed double-precision (64-bit) floating-point elements in a, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set). The maximum relative error for this approximation is less than 2^-14.
