  40         <para>
  41             <function>unpackDouble2x32</function> returns a two-component unsigned integer vector
  42             representation of <parameter>d</parameter>. The bit-level representation of <parameter>d</parameter> is
  43             preserved. The first component of the returned vector contains
  44             the 32 least significant bits of the double; the second
  45             component consists the 32 most significant bits.
