# XQuery Numeric Operators Reference

This section provides descriptions of the XQuery numeric operators available in the mapper functionality of WebLogic Workshop. You use the mapper functionality to generate queries and to edit these queries to add invocations to these provided XQuery operators. To learn more, see Invoking Functions or Operators in a Query.

In addition to the XQuery functions and operators available in the mapper functionality, a larger set functions and operators is provided. You can manually add invocations to these functions and operators to queries in the Source View of the mapper functionality. For a list of these additional functions and operators, see the XQuery 1.0 and XPath 2.0 Functions and Operators - W3C Working Draft 16 August 2002 available from the W3C Web site at the following URL:
