How can we use CAST() Function ?

CAST() function is used to converts a value of one data type into another data type. The semantics of CAST is the same as the semantics of corresponding TO_DATATYPE conversion.

• If the scale is not sufficient to hold the value, then the function rounds the value.
• If the precision is not sufficient to hold the value, then the function will raise the error.
