But... I've also heard the very similar a**b is a multiplied by a b-1 times. That gives 0**0=0*(1/0). Uh, Oh! If you want consistency with the treatment of exponents that might cause problems. Tough situation when you have a "discontinuity" at 0 for x^x. -- -- Lou Pecora -- http://mail.python.org/mailman/listinfo/python-list
