Custom PID: What functions can you use?

I looked all over the site. Can anyone direct me to the types of mathematical functions that you can use when making a custom PID?

I would like to check one variable to help determine the outcome of the PID. Possibly, do some filtering/refining during the logging. Just not sure of the syntax of used in EFILive.


E.G.

If ( [This GM PID] > 0){
Custom PID ~= Custom PID
};

Just a random example. Not applied to what I want to achieve.
Thank you in advance.

You want to do this:

Code:

---

iff({GM.PID} > 0, ~{CUSTOM.PID}, {CUSTOM.PID})

Pids are always enclosed in braces { }.

Oh neat! Is there a file with a complete list somewhere?
