Expression Builder

Use the Expression Builder, which appears in a variety of rule forms, to author arithmetic or logical expressions in a natural language format.

For example, you can compute an employee's salary by defining a calculation that uses properties, such as number of years employed, employee review rating, and job grade level.

It provides the following features:

• The ability to use single or multi-line comments.
• Formatting that persists after you close the Expression Builder. Any tab characters, carriage returns, and whitespaces are preserved the next time you open the Expression Builder.
• Real-time validation of expressions. The Expression Builder detects any errors in your syntax as you enter the expression.
• The ability to test the input value of a property for a portion or all of the expression.
