pub unsafe fn _mm512_maskz_rsqrt14_ps(k: u16, a: __m512) -> __m512🔬This is a nightly-only experimental API. (
stdarch_x86_avx512)Available on 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.
