# Function core::arch::x86::_mm_maskz_rcp14_pd
[−][src]

    pub unsafe fn _mm_maskz_rcp14_pd(k: __mmask8, a: __m128d) -> __m128d

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512f,avx512vl` only.
Expand description

Compute the approximate reciprocal 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.
