rel_exp - Comparing Elementary Data Types
If operand1 and operand2 in a relational expression have elementary data types, they are used to determine a common elementary

comparison type

whose rules are used to perform the comparison. Operands that are not compatible with the comparison type are converted to this type. Comparisons with elementary comparison types are

comparisons of elementary data objects

comparisons of calculation expressions

The return values or results of functional methods, predefined functions, constructor expressions, and table expressions are handled like elementary data objects.

Notes

Previous assignments made to helper variables with certain types or the conversion operator CONV can be used to force comparison types and conversions other than a direct comparison of the operands.

It should be noted that some predefined functions operate like an arithmetic expression if they contain a numeric expression as an argument.
