In all except the base version of LabVIEW, you've got the Eval Formula Node (Analyze>Mathematics>Formula palette) and the functions under the Analyze>Mathematics>Formula>Advanced Forumla Parsing palette. The formulas have to adhere to a certain syntax or you modify the strings match the acceptable syntax in LabVIEW but I think these are what you're looking for.
