Abs and variables
Posted:
Jun 18, 1996 3:08 AM


How can I have the Abs function treat real variables properly? I seem to recall a way of declaring a variable real, but I don't remember how. If there is such a way, would this work with Abs; i.e. fix the variable a so that "Abs[a]" will give a result of "a"?
Thanks.
