As discussed in xref:type/index.adoc[Data Types], the `data-1` +field may be interpreted as a reference to an attribute. + +The `data-2` field is interpreted in a type-specific manner. For +example, if `data-1` refers to an attribute of type `ipaddr`, then +`data-2` is evaluated as an IP address. If `data-1` refers to an +attribute of type `integer`, then `data-2` is evaluated as an integer +or as a named enumeration defined by a `VALUE` statement in a +dictionary. Similarly, if `data-1` refers to an attribute of type +`date`, then `data-2` will be interpreted as a date string. + +If the resulting data evaluates to be the same, then the operator +returns `true`; otherwise, it returns `false`. + +.Example +[source,unlang] +---- +if (User-Name == "bob") { + ... +} +---- + +// Copyright (C) 2020 Network RADIUS SAS.
