Function core::arch::x86::_mm512_maskz_rsqrt14_pd
source · pub unsafe fn _mm512_maskz_rsqrt14_pd(k: __mmask8, a: __m512d) -> __m512d🔬This is a nightly-only experimental API. (
stdsimd #48556)Available on (x86 or x86-64) and target feature
avx512f only.Expand description
Compute the approximate reciprocal square root of packed double-precision (64-bit) floating-point elements in a, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set). The maximum relative error for this approximation is less than 2^-14.
