Before Change

        from sympy.series.order import Order
        nu, z = self.args

        if z.limit(x, 0) is S.Zero:
            s = [(-1)**k * z**(2 * k) / (factorial(k) * factorial(nu + k)
                    * 2**(2 * k)) for k in range((n + 1)//2)] + [Order(z**(n))]
            return ((z / 2)**nu * Add(*s)).expand()

After Change

        try:
            _, exp = z.leadterm(x)
        except (ValueError, NotImplementedError):
            return self

        if exp.is_positive:
            newn = ceiling(n/exp)
            s = [(-1)**k * z**(2 * k) / (factorial(k) * factorial(nu + k)
