The IEEE standard specifies (plus or minus) infinity as the result of division by zero. This makes sense since such is the limit of division by a quantity that goes to zero. The IEEE standard then goes on to define reasonable results for arithmetic between infinities and real values. The production of, and arithmetic on, infinities is a choice that any application may want allow or not. Gary Herron -- http://mail.python.org/mailman/listinfo/python-list
