Function core::arch::x86::_mm_maskz_rsqrt14_pd [−][src]
pub unsafe fn _mm_maskz_rsqrt14_pd(k: __mmask8, a: __m128d) -> __m128d
This 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 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.
