Online Scientific Calculator
About This Scientific Calculator
This advanced online Scientific Calculator, brought to you by Sustainable Digital Shop, is designed to help you with a wide range of mathematical tasks, from simple arithmetic to complex scientific and engineering calculations. It operates entirely within your browser, ensuring your data remains private.
Key Features:
- Standard Arithmetic: Addition, subtraction, multiplication, division.
- Trigonometric Functions: sin, cos, tan, and their inverses (asin, acos, atan) with support for both Degrees (DEG) and Radians (RAD) modes.
- Logarithmic Functions: Natural logarithm (ln) and base-10 logarithm (log).
- Exponents & Roots: Powers (xy, x2, x3, 10x), square root (√), cube root (3√).
- Factorial (n!): Calculate the product of all positive integers up to n.
- Constants: Easy access to Pi (π) and Euler’s number (e).
- Percentage (%): Quick percentage calculations.
- Memory Functions: Store (M+), subtract from (M-), recall (MR), and clear (MC) values in memory.
- Parentheses: For grouping expressions and controlling order of operations.
- History & Clear: View your ongoing expression and clear entries or all calculations.
How to Use:
- Use the number buttons (0-9) and the decimal point (.) to input numbers.
- Select operators (+, -, ×, ÷) for basic arithmetic.
- Utilize function buttons (sin, cos, log, √, xy, etc.) for advanced calculations. Many functions will automatically add an opening parenthesis `(` – you’ll need to input the argument and the closing parenthesis `)`.
- Toggle between **DEG** (Degrees) and **RAD** (Radians) mode for trigonometric functions using the dedicated button.
- Press **=** to evaluate the current expression.
- **AC** (All Clear) resets the calculator completely. **DEL** (Delete/Backspace) removes the last entered digit or operator from the current input.
- Use **M+**, **M-**, **MR**, **MC** for memory operations.
Note on `eval()`: This calculator uses JavaScript’s `eval()` function to compute results. The input to `eval()` is constructed from your button presses and transformed to use JavaScript’s `Math` object, minimizing risks associated with `eval()` for this specific application.
Frequently Asked Questions (FAQ)
Q1: Is this scientific calculator free to use?
Yes, this online scientific calculator is completely free to use, provided by Sustainable Digital Shop.
Q2: How do I switch between Degrees and Radians for trigonometric functions?
Use the button labeled “DEG” or “RAD” (it toggles). The current mode is displayed on the button. Ensure you are in the correct mode before performing trigonometric calculations.
Q3: How does the percentage (%) button work?
When you enter a number and press the % button, it converts that number to its decimal equivalent (e.g., 50 % becomes 0.5). This value is then used in the ongoing calculation. For example, `100 + 50 %` would be interpreted as `100 + 0.5`.
Q4: What if I make a mistake while typing?
Use the **DEL** (Delete/Backspace) button to remove the last character entered in the current number. If you need to clear the entire current entry or start over, use **AC** (All Clear).
Q5: Are my calculations stored or sent to a server?
No. All calculations are performed locally in your web browser using JavaScript. No data is sent to or stored on any server, ensuring your privacy.
