Full-Featured Scientific Calculator

Experience the power and precision of a classic scientific calculator right in your browser. This full-featured tool is designed for students, engineers, and professionals, offering a comprehensive suite of mathematical functions, proper order of operations (PEMDAS/BODMAS), advanced memory capabilities, and full keyboard support. It's a robust and reliable tool for tackling everything from simple arithmetic to complex trigonometric and logarithmic equations.

How It Works

Our calculator is designed to function just like a traditional scientific calculator, with a powerful engine to handle complex expressions.

  1. Enter Your Calculation: Use the on-screen buttons or your keyboard to input numbers, operators, and functions.
  2. Use Advanced Functions: Access secondary functions like inverse trigonometry using the "2nd" key. Switch between Radians and Degrees mode for trigonometric calculations.
  3. Get Accurate Results: The calculator correctly evaluates expressions using the order of operations, and you can use parentheses for complex grouping.

Key Features

  • Correct Order of Operations (PEMDAS): Powered by a stack-based calculation engine, the tool correctly evaluates complex expressions, respecting the standard mathematical order of operations. It fully supports nested parentheses for grouping.
  • Comprehensive Scientific & Mathematical Functions:
    • Basic Arithmetic: Addition, Subtraction, Multiplication, Division, and Percentage.
    • Trigonometric Functions: Sine (sin), Cosine (cos), Tangent (tan), and their inverses (sin⁻¹, cos⁻¹, tan⁻¹) accessible via the "2nd" key.
    • Hyperbolic Functions: sinh, cosh, tanh, and their inverses (sinh⁻¹, cosh⁻¹, tanh⁻¹).
    • Logarithmic Functions: Natural Log (ln), Base-10 Log (log), and Base-2 Log (log₂).
    • Powers & Roots: `x²`, `x³`, `xʸ`, Square Root (√), and the y-th root of x (ˣ√y).
    • Exponents: `eˣ` and `2ˣ`.
    • Constants & Other: Pi (π), Reciprocal (1/x), Factorial (x!), and a Random Number Generator.
  • Full Keyboard Control: Nearly every function is mapped to a keyboard shortcut (e.g., 's' for sin, 'l' for ln, 'p' for π), allowing for rapid, power-user calculations.
  • Advanced Display & Formatting:
    • Handles large numbers with scientific notation.
    • Customizable number grouping: Choose between dots, commas, or a mix for thousands separators to match international standards.
  • Full Memory Functions: Standard memory keys including Memory Clear (mc), Memory Recall (mr), Memory Add (m+), and Memory Subtract (m-).
  • Radians and Degrees Modes: Easily switch between RAD and DEG modes for all trigonometric calculations, with the current mode always visible.
  • Persistent State: The calculator automatically saves its entire state—including the current number, your ongoing calculation, the value in memory, and your RAD/DEG setting—to your browser. You can refresh the page and resume your work right where you left off.
  • Convenient Tools: Includes one-click Copy and Paste functionality, a resizable interface, and clear visual feedback for active operations and modes.

How to Use the Calculator

  1. For Complex Expressions:
    Type an equation like `( 5 + 3 ) * 2 =`. The calculator will correctly evaluate the parentheses first, yielding 16.
  2. Using the "2nd" Key:
    To calculate the arcsin of 0.5, press `2nd`, then `sin` (which now shows sin⁻¹), then `0.5`, and finally `=`.
  3. Using Memory:
    Enter a number and press `m+` to add it to memory. Press `mr` to recall it for use in another calculation. `mc` clears the memory.
  4. Switching Trig Modes:
    Click the "Rad" or "Deg" button to toggle between Radians and Degrees. The display will update to show the current mode.
