### BINARY-*

multiplication function

    Major Section:  ACL2-BUILT-INS

Completion Axiom (`completion-of-*`):

    (equal (binary-* x y)
           (if (acl2-numberp x)
               (if (acl2-numberp y)
                   (binary-* x y)
                 0)
             0))

Guard for `(binary-* x y)`:

    (and (acl2-numberp x) (acl2-numberp y))

Notice that like all arithmetic functions, `binary-*` treats non-numeric inputs as `0`.

Calls of the macro `*` expand to calls of `binary-*`; see *.
