Frequently Asked Questions

Find answers to common questions about our scientific calculator

How accurate is the scientific calculator?

Our scientific calculator provides high-precision calculations with up to 15 decimal places of accuracy. It uses JavaScript's built-in Math library which follows IEEE 754 standards for floating-point arithmetic.

Can I use parentheses in my calculations?

Yes, you can use parentheses to control the order of operations. The calculator follows standard mathematical precedence rules (PEMDAS/BODMAS), but parentheses allow you to explicitly define the calculation order.

Does the calculator support complex numbers?

Currently, our calculator focuses on real number calculations. While it supports advanced functions like trigonometry and logarithms, complex number operations are not available in this version.

Can I use the calculator on my mobile device?

Absolutely! Our scientific calculator is fully responsive and works perfectly on all devices including smartphones and tablets. The interface adapts to different screen sizes for optimal usability.

Is there a way to see my calculation history?

Yes, the calculator displays your current expression above the result. While we don't store a permanent history, you can see and edit your current calculation expression at any time.
