Function core::arch::x86_64::_mm_maskz_rsqrt14_ps

pub unsafe fn _mm_maskz_rsqrt14_ps(k: __mmask8, a: __m128) -> __m128

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512f,avx512vl and x86-64 only.

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.
