Expand description

Compare packed half-precision (16-bit) floating-point elements in a and b, and store packed maximum values in dst using writemask k (elements are copied from src when the corresponding mask bit is not set). Does not follow the IEEE Standard for Floating-Point Arithmetic (IEEE 754) maximum value when inputs are NaN or signed-zero values.
