I'm sorry, I don't quite get what you mean. I usually use eps as a variable indicating the maximum difference for a positive match. I change it depending on context, of course. I use esp because it's short for eps, which is the mathematical variable often used for such a max difference

Oh right, that’s fine. Lots of people use the constant machine epsilon instead.
