	And, of course, this applies even to binary when yy is a
	singleton integer for the denominator is 1 in that case. :-)

	It is the odd integers that produce the negative results
	in case of xx < 0, the even integers produce positive
	results, & both cases will probably be sent to one of
	the other pow's in any practical implementation.
	
	But things like this & many others are kind of the idea
	behind a generalized pow, no?

	The pow that covers all cases & contains all solutions.
