https://community.blueprism.com/t5/Product-Forum/Minimal-functions-available-for-expressions/m-p/54326#M8866 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 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]?
