>>convoluted code? what's that comparison for?

getting the right answer for unsigned to double conversion.
if the integer value is negative, the conversion needs
to add 2^32 to adjust it.
i haven't looked it up but i imagine that the stcw/ldcw is to
set the control word to the right rounding mode for the conversion,
because it's in a global machine word not the instruction.
the source operand is required to be a memory location.
