problems with lookup~ around zero

    Hi listmembers,
    Realizing that a lookup~ table was not doing what I wanted it to do I was trying to build a simple input = output table.
    I could not get rid of the problem that if I input values little below zero, the lookup~ object gives me positive values instead of negative ones. What I need is the lookup~ object beeing able to deal with negative values as proper as it does with positive values.
    A patch to illistrate the problem is below.
    I'd be glad for hints to solve this problem.
    Thanks and best, Cor
