    Re: Absolute Value

    Abs returns the absolute value ("modulus") of a number, effectively making all numbers positive. Here is example input and output:
    abs(-2) = 2
    abs(-1) = 1
    abs(0) = 0
    abs(1) = 1
    abs(2) = 2

    It is good for when dealing with difference, when positive and negative don't matter. For example you can use abs(A-B) to get the difference between two Values. If A were 4 and B were 6 then abs(A-B)=abs(4-6)=abs(-2)=2. While you can multiply a negative by -1 to make it positive, this would also make a positive a negative (which isn't good if A were 6 and B were 4).

    Re: Absolute Value

    OliverPearl, modulos is the latin word for absolute value.
    You probably thought of the operator which has almost the same name, modulo (mod).

    Re: Absolute Value

    Modulus is actually the latin word for "a small measure" and is a diminutive of modus meaning "measure" (as well as other things like 'limit' and 'amount').
