🔬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 of packed 16-bit floating-point elements in a
and stores 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
.
