I think n is always non-negative in the trig series, but some Laurent series use negative n values. So (-1)^^n might be useful for negative n, but you could always rewrite it as (n%2 ? -1 : 1) or ~(n&1)+1.
Oops, ~(n&1)+1 doesn't work, but ~((n&1)<<1)+2 does. -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/
