Expand description

Convert the lower half-precision (16-bit) floating-point element in b to a double-precision (64-bit) floating-point element, store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper element from a to the upper element of dst.

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