Good questions. Simple answers.
Is difference the same as percentage change?
No. From 100 to 120, percentage increase is 20%, but percentage difference is about 18.18%, because its reference is 110.
What happens if one or both values are zero?
One zero and one positive value give 200%. We define the difference between two zero values as 0% for this calculator. Negative quantities are not supported.
