pub unsafe fn _mm256_rsqrt_ph(a: __m256h) -> __m256h🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature
avx512fp16,avx512vl and x86 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.
The maximum relative error for this approximation is less than 1.5*2^-12.
