🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16)

Available on x86-64 only.

Convert the lower double-precision (64-bit) floating-point element in b to a half-precision (16-bit) floating-point elements, store the result in the lower element of dst using writemask k (the element if copied from src when mask bit 0 is not set), and copy the upper 7 packed elements from a to the upper elements of dst.
