Function core::arch::x86::_mm256_mask_rsqrt14_ps

pub unsafe fn _mm256_mask_rsqrt14_ps(
    src: __m256, 
    k: __mmask8, 
    a: __m256
) -> __m256

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

This is supported on x86 and target feature avx512f,avx512vl 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 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.
