Scientific Calculator

A feature-rich scientific calculator built with Java Swing, supporting arithmetic, trigonometric, logarithmic functions, memory operations, and a calculation history log.

Features

• Basic arithmetic: +, -, *, /, %
• Scientific functions: sin, cos, tan, √, log, ln, 10^x, !
• Memory operations: M+, M-, MR, MC
• Keyboard input support (with some limitations, e.g., 9/10 via keyboard needs button input workaround)
• History log of calculations
• Color-coded UI with hover effects

Usage

• Run Calculator.java with a Java compiler (e.g., javac Calculator.java and java Calculator).
• Use buttons or keyboard for input (note: for 9/10, use buttons to avoid syntax errors).
• Clear with C (clear entry) or CE (clear all).

Known Issues

• Keyboard input for expressions like "9/10" results in a syntax error (use buttons as a workaround).
