Function core::arch::x86::_mm256_mask_rsqrt14_pd   [−][src]
pub unsafe fn _mm256_mask_rsqrt14_pd(
    src: __m256d, 
    k: __mmask8, 
    a: __m256d
) -> __m256dThis is supported on x86 and target feature 
avx512f,avx512vl 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 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.
