A non-FLOAT arg is converted to a FLOAT value, based on implicit type conversion rules. If the argument cannot be converted, an error is reported. For more information, see Data Type Conversions.
Hyperbolic and inverse hyperbolic functions cannot be applied to the following types of arguments:
- BYTE or VARBYTE
- BLOB or CLOB
- CHARACTER or VARCHAR if the server character set is GRAPHIC
