Is there any node in xod that inverts a value from positive to negative? I can’t find it and I don’t know what it’s called in English. Example input 8 and the output would be -8 It is something easy to implement in c ++ but if it is a native xod node I would like to use it. ---

Use the multiply node 8 x -1 = -8 ---

I had thought, also to make a node that sends the negative value of input to the output. I think that is the simplest thanks ---
