Whoops, big fat mistake there, all the deltas can of course be negative. So given the various alternatives, losing one bit of exponent for all deltas is clearly the right thing to do. Parameter values are nonnegative as originally claimed, and the extra range could conceivably be worth something in some cases, so lose the sign bit instead.
