Expand description

Convert packed half-precision (16-bit) floating-point elements in a to packed double-precision (64-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).

Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
