Function core::arch::x86::_mm512_mask_rsqrt14_pd [−][src]
pub unsafe fn _mm512_mask_rsqrt14_pd(
src: __m512d,
k: __mmask8,
a: __m512d
) -> __m512d
This is supported on x86 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 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.
