pub unsafe fn _mm256_mask_rsqrt14_ps(src: __m256, k: u8, a: __m256) -> __m256🔬This is a nightly-only experimental API. (
stdarch_x86_avx512)Available on x86-64 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 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.
