Parametric modeling logic

[BLDG_orange]

What level of expression complexity is possible from within the "Change Parameters" window, without writing an API? Is there a list of operations (relational/conditional/arithmetic/etc.) showing capability and language format?

For example, I would like to define a pattern count based on an expression rounded to the nearest whole number.

Here's a link to the Help it's hidden under Change Parameters.

Mark... Thanks for the response. 

Do you have any experience using "; delimiter for multiargument functions"? I'm curious what an example would be for this. The functions I need to use require IF/Then statements. I'm wondering if the link you provided is the complete list of functions. If so, what would be the best way to drive a design that requires conditional logic?

I afraid there's no way to do any sort of logic if\then testing in the parameters dialog. Your only option at the momment would be to use the API here's the API Help.
