Converting date and time information  Arithmetic overflow and divide-by-zero errors

Chapter 2: Transact-SQL Functions

Converting between numeric types

You can convert data from one numeric type to another. Errors can occur if the new type is an exact numeric with precision or scale that is not sufficient to hold the data.

For example, if you provide a float or numeric value as an argument to a built-in function that expects an integer, the value of the float or numeric is truncated. However, Adaptive Server does not implicitly convert numerics that have a fractional part but returns a scale error message. For example, Adaptive Server returns error 241 for numerics that have a fractional part and error 257 if other datatypes are passed.

Use the arithabort and arithignore options to determine how Adaptive Server handles errors resulting from numeric conversions.
