Which restrictions exist for ABAP SQL arithmetic expressions?

In ABAP SQL arithmetic expressions, it is significant to understand the behavior of different data types during operations. When floating point types and integer types are used in the same arithmetic expression, it can lead to unexpected results or even errors due to differences in precision and representation.

ABAP enforces strict rules when it comes to mixing these types. Floating point numbers have a broader range and a different handling of precision compared to integer types. If both types are used together in an expression, the result may not be as precise as expected. Therefore, to maintain accuracy and reliability in calculations, using floating point types and integer types together is restricted.

This ensures that developers avoid pitfalls associated with type conversion and maintain the integrity of numerical operations within their programs.
