Inheritance¶
Description¶
The TFPUnequalOperation class implements the inequality comparison operation (<>) between two operands of compatible types. It extends TFPBooleanResultOperation to provide inequality-specific comparison logic.
The operation compares two values and returns True if they are not equal, False if they are equal. It handles different data types appropriately, using numeric comparison for numbers, string comparison for strings, and boolean comparison for boolean values.
Type conversion is performed when necessary to compare values of different but compatible types, ensuring that the inequality test works across different numeric types.
