Expand description

Convert the lower half-precision (16-bit) floating-point element in b to a single-precision (32-bit) floating-point element, store the result in the lower element of dst using writemask k (the element is copied from src to dst when mask bit 0 is not set), and copy the upper 3 packed elements from a to the upper elements of dst.

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