pub unsafe fn _mm256_mask_rsqrt_ph(src: __m256h, k: u16, a: __m256h) -> __m256h🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16)Available on x86-64 only.
Expand description
Compute the approximate reciprocal square root of packed half-precision (16-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 1.5*2^-12.
