Built-in functions

A built-in function returns a value calculated from one or more value node parameters. The tool tip shows the number of parameters required for the function.

There are several types of built-in function that work with different types of data:

· Geometry

· Conversion

· Mathematical

· Bit manipulation

· String

· Collection

· Topological

· Timestamp

· User-defined

Users can add their own built-in functions by writing Java classes. For more information, see the 1Integrate Programmer's Reference Guide. A list of the built-in functions are as follows:
