Re-orienting rotation 0 point?

Thanks for the response!

Hmm. I’m not quite very savvy with math so I’m not sure what’s going on here, or how to add sign() to something. Attached is what I have so far.

I multiplied the end value by 100 because all I was getting was numbers between 0 and 2.4 … but its still not quite working. I am certain I’m not following your instructions somehow. Any help would be appreciated!
