Expand description

Convert packed double-precision (64-bit) floating-point elements in a to packed half-precision (16-bit) floating-point elements, and store the results in dst using writemask k (elements are copied from src to dst when the corresponding mask bit is not set). The upper 64 bits of dst are zeroed out.
