Function core::arch::x86_64::_mm256_maskz_rcp14_pd [−][src]
pub unsafe fn _mm256_maskz_rcp14_pd(k: __mmask8, a: __m256d) -> __m256d
This is supported on x86-64 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.
