Minimal functions available for expressions

[BenCodiroli]

Why are there so few functions available for use in Expressions, specifically with Number functions? I'm looking for a simple Max() function to just return the max of 2 numbers for use in an expression and this is not an option. Is there any way to import or create new functions for use in Expressions?

If the data source is a column in a collection, you can use Linq to run aggregate SQL queries against the DataTable, such as max(). If you're only working with two numbers though, it should be fairly simple with a decision stage to see which is larger. [Decision][x]>[y]? Yes -     [Calculation]In: [x]; Out: [Value] No -     [Calculation]In: [y]; Out: [Value]

I was hoping to be able to use a Max function inside of a longer expression, but I guess I could create a new stage and variable to perform that calculation prior to the expression...that's just not ideal.
