Frequently Asked Questions

What is the difference between DEG and RAD mode?

DEG (degrees) uses the 360-degree system where a full circle is 360°. RAD (radians) uses the radian system where a full circle is 2π. Most everyday calculations use degrees.

What is the maximum factorial this calculator supports?

This calculator supports factorials up to 170! JavaScript numbers cannot accurately represent values larger than that.

Can I use my keyboard?

Yes! Use number keys (0-9), operators (+, -, *, /), parentheses, Enter or = to evaluate, Backspace to delete, and Escape to clear.
