Predefined constants in the System Library

Predefined constants appear in:

• The Constants tab of the System Library.
• The Rule Wizard > Expression tab > Constants tab in the System Library or in a study. Predefined constants do not appear in this location for user-created libraries.

When your Libraries Browser searches include the System Library, the predefined constants are included in the search.

In the Rule Wizard, when you drag a function to the Expression workspace, the Invoke Function dialog box appears. In the dialog box, you can expand the Constants tab, and drag the appropriate constant to the Value field for the parameter.
