Description:
Implement an exponentiation feature within the calculator UI to allow users to easily perform power calculations (e.g., 2^3 = 8).
Tasks:
UI Enhancement:
Design and integrate a new button labeled ^ or ** within the existing calculator interface.
Ensure the button placement is intuitive and consistent with the overall UI design.
Logic Implementation:
Develop the underlying logic to handle exponentiation, ensuring it correctly interprets inputs and returns the expected results.
