Synopsis
_mm512_maskz_cvtne2ps_pbh(__mmask32 k, __m512 a, __m512 b);
Description
Convert packed single-precision (32-bit) floating-point elements in two vectors "a" and "b" to packed BF16 (16-bit) floating-point elements, and store the results in single vector "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation

ELSE
dst.word[j] := 0
