Parameters

Keyword	Type	Description
typeNumber	Number (Integer)	The type to which the value should be cast. This may be retrieved by using typeof(x), where x is a value of the intended type, or referencing a type with 'type!{namespace}type-name' (within single quotes).
value	Any Type	The value that should be cast to type typeNumber.

Returns

Any Type

Usage considerations

Referencing data types

• To retrieve the type number, use typeof(x), where x is a value of the intended type, or reference a type with type!{namespace}type-name (within single quotes).
• When referencing a data type, consider the impact that deleting the data type has on the expression that references it.

Use in portals

• In portals, you cannot cast a value to a record type.

Examples

cast('type!{http://www.appian.com/ae/types/2009}Integer', 123.4) returns 123

cast(1, 123.4) returns 123
