Calc 5

This document contains the code for a basic calculator application. It defines click event handlers for buttons 0-9 and arithmetic operation buttons that append numbers to a text box. Additional buttons clear the text box, evaluate expressions based on the operation type, and insert a decimal point if one is not already present. The application performs basic number input, arithmetic calculations, and output to a text box for display.
