Dual Direction Math Changing a value from Negative to Positive

Hi Andy,

There are a number of ways to handle this but I think the easiest way is to use a state parameter:

Thank you very much Tim. 
I realize now that I did not fully understand a multi- vector object. That answers my question.

Just for interests sake, however, would you mind posting a few of theother methods that you mentioned?

Thank you.

You did not mention the setup of your joystick.

Assuming you are using a 0.5V to 4.5V signal range where 2.5V would be your center voltage.

Perhaps look at your input configuration.

Now that the Joystick has a range of -100 to 100 you can add a simple math object with the multi vector to setup a "deadzone" in this case the "deadzone" is within -5% to +5%, From 5% above or below -5% the output value would be porpotional in the respective direction. 

Perhaps if possible explain a bit more about your setup, like joystick/signal type. 

Hope you come right.

You are correct about the input config.

I am using a joystick with input from 0.5-4.5 volts and a 10% deadband as default via a multi- vector object.

Please see the attached project that is doing as I want according to Tim Reen's suggestion. It was simply for interest's sake that I wanted to know more methods of doing it as Tim suggested that there might be other ways.                                               Joystick Crossed Signals Example.idax

Hi Andy,

Here is an example using a digital parameter:

And with this example you could use a physical digital input:

Thank you very much for your assistance Tim!

I appreciate your time and clear examples for a newbie like me.
