Arguments that are not FLOAT are converted to FLOAT based on implicit type conversion rules. See Teradata Vantage™ - Data Types and Literals, B035-1143. If an argument cannot be converted, an error is reported.
- The UDT must have an implicit cast to any of the following predefined types:
To define an implicit cast for a UDT, use the CREATE CAST statement and specify the AS ASSIGNMENT clause. See Teradata Vantage™ - SQL Data Definition Language Syntax and Examples, B035-1144.
- Implicit type conversion of UDTs for system operators and functions, including trigonometric and inverse trigonometric functions, is a Teradata extension to the ANSI SQL standard. To disable this extension, set the DisableUDTImplCastForSysFuncOp field of the DBS Control Record to TRUE. For details, see Teradata Vantage™ - Database Utilities , B035-1102 .
- BYTE or VARBYTE
- BLOB or CLOB
