how to compute difference between numers?

    I don't remember if there is any object that can calulate the difference between two numbers:
    esample:
    22 and 40 = 18 29 and 26 = 3
    I don't use a "-" for I don't want negative numebrs: like:
    22 -40 = -18
    It would be interesting if I could have the same operation done with lists of numbers:
    22 10 55 66 23 VS 40 50 60 20 125 = 18 40 5 46 102

      You could use "abs" after "-" to avoid negative numbers.

      DOH! thanks! my memory is getting rusty..
      can i also compute lists?

      yes [abs] is the right way. You could use [vexpr] object to compute the difference between two lists, check [vexpr] help.
      cheers

      Actually and for the record, you *can* do this with a single external. If you want to.
      I was going to point you to www.maxobjects.com, but I see that the object in question hasn't been listed there yet. Solo culpa mea. So I fear I will, yet again, have to resort to a plug.
      The object is called lp.delta. URI below.

      Sorry, I meant to add that the fact that lp.delta is missing is nobody's faux mais de moi.
      My internet access is limited to a dial-up while I am in the US, perhaps to the relief of some list readers. So updating my babies will remain, FBOW, on the to-do list until I get back to Berlin.
      Great work on maxobjects.com, it's a great resource that I plug, well, not quite as much as Litter Power or iCE, but close.
