Frequently Asked Questions

Is this advanced calculator completely free to use?

Yes, our scientific calculator is completely free with no hidden fees, registration requirements, or usage limits. Access all advanced mathematical functions without any cost or restrictions.

What's the difference between degrees and radians mode?

Degrees mode uses the familiar 360-degree circle system (sin(90°) = 1), while radians mode uses the mathematical standard where a full circle equals 2π radians (sin(π/2) = 1). Toggle between modes using the DEG/RAD switch based on your calculation requirements.

Can I use keyboard shortcuts with this calculator?

Absolutely! The calculator supports full keyboard input including numbers (0-9), basic operators (+, -, *, /), Enter for equals, Escape for clear, and Backspace for delete. This makes calculations faster and more efficient.

How accurate are the mathematical calculations?

Our calculator uses JavaScript's built-in mathematical functions, providing high precision for most calculations. Results are accurate to approximately 15-16 significant digits, suitable for academic, professional, and scientific applications.

Does the calculator work on mobile devices?

Yes, the calculator is fully responsive and optimized for mobile devices, tablets, and desktop computers. The button layout automatically adjusts for touch interfaces while maintaining full functionality across all screen sizes.
