Key Functions & Capabilities
- Trigonometry: Calculate Sine (sin), Cosine (cos), and Tangent (tan) instantly. The calculator operates in Radians by default, ensuring compatibility with standard higher-math formulas.
- Logarithms & Exponents: Effortlessly compute Natural Logs (ln), Base-10 Logs (log), powers (x^y), squares (x²), and the mathematical constant 'e' (Euler's number).
- Roots & Constants: Access square roots (√), Pi (π ≈ 3.14159), and factorial operations (!) for probability and statistics.
- Memory Functions: Use parentheses ( ) to enforce strict order of operations (BODMAS/PEMDAS) for complex, multi-step equations.
Frequently Asked Questions
Are trigonometric functions calculated in Degrees or Radians?
By default, standard scientific functions like sin(), cos(), and tan() in this calculator operate using Radians, which is the standard for JavaScript and advanced calculus. If you need degrees, you must convert the value manually (Degrees × π / 180).
What is the order of operations?
The calculator strictly adheres to the standard BODMAS / PEMDAS rules. It will evaluate Parentheses first, then Exponents (Orders/Roots), followed by Multiplication and Division, and finally Addition and Subtraction.
Is there a limit to how large a number can be calculated?
The calculator uses standard double-precision 64-bit floating-point format (IEEE 754). It is highly accurate up to 15-17 significant decimal digits. Extremely large factorials or exponents exceeding browser memory limits will return "Infinity".
Is this calculator free to use?
Yes, 100% free with no intrusive popup ads, no registration required, and no limits on the number of calculations you can perform.
