Completion Axiom:
(equal (unary-/ x)
(if (and (acl2-numberp x)
(not (equal x 0)))
(unary-/ x)
0))
Guard for (unary-/ x):
(and (acl2-numberp x)
(not (equal x 0)))
Notice that like all arithmetic functions, unary-/ treats
non-numeric inputs as 0.
Calls of the macro / on one argument expand to calls of
unary-/; see /.
