Frequently Asked Questions

Is this calculator free to use?

Yes, our scientific calculator is 100% free and requires no registration or software installation.

Does it support degrees or radians?

Currently, the trigonometric functions use the standard JavaScript Math library, which typically accepts input in radians. You may need to convert degrees to radians (multiply by π/180) for certain calculations.

Can I use this on my phone?

Absolutely! The interface is fully responsive and optimized for touch screens on mobile devices.

How accurate is the calculator?

It uses standard double-precision floating-point arithmetic (IEEE 754), which provides high accuracy for most scientific and engineering applications, up to 15-17 decimal digits.
