Description¶
The TFPPowerOperation class implements the power (exponentiation) operation for raising one numeric value to the power of another. It extends the mathematical operation framework to provide exponentiation functionality with proper type handling.
The power operation supports integer, float, and currency operands, automatically promoting the result type to ensure sufficient precision. The operation follows standard mathematical rules for exponentiation including handling of negative bases and fractional exponents.
This class is used internally by the TFPExpressionParser class to construct an AST (Abstract Syntax Tree). There is normally no need for you to use or instantiate this class directly.
