Did the Analytical Engine have a minus Zero in addition to a the normal (plus) zero?
In other words:
If two equal negative numbers were subtracted, was the result a positive zero, and the run-up lever set due to the rule that the signs differ?
Or was the run-up lever clear, and a negative zero produced?
Or was a (positve) zero produced, and the rule that the run-up lever set if the signs differ overridden, once the result is zero?
