I still have some rot in my head, from too much java, and so I don't 
think consistently clearly, it's more cyclic I've noticed. As a result, 
my eyes are doing back-flips when looking at this code; perhaps I need 
eine kleine pause...does anyone else want to try it?

     int termPlus1 = ((term & 0x1) == 0) ? (term | 1) : (term & ~1);

cheers,
Robert

ps. an example of Java conciseness, dear God.
