Function core::arch::x86::_mm512_maskz_rsqrt14_ps
source · pub unsafe fn _mm512_maskz_rsqrt14_ps(k: __mmask16, a: __m512) -> __m512🔬This is a nightly-only experimental API. (
stdsimd #48556)Available on (x86 or x86-64) and target feature
avx512f and x86 only.Expand description
Compute the approximate reciprocal square root of packed single-precision (32-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.
