The Evaluate Expression step is used to solve a defined algebraic expression. The step achieves this by automatically creating input for characters representing the numeric variables in the Expression. This can be helpful for people in fields such as banking or engineering, where they may need to evaluate a custom formula with data values from another step.
These steps use NCalc expressions. For more information, see NCalc.
