How do I toggle between Degrees and Radians?

Click the "Deg / Rad" toggle button on the calculator keypad to switch trigonometric evaluation modes.

Can I use my computer keyboard to type calculations?

Yes. The calculator accepts standard number keys, operators (+, -, *, /), decimal points, Enter for equals, and Backspace to delete.

Does this calculator respect standard order of operations (PEMDAS/BODMAS)?

Yes. Parentheses, exponents, multiplication, division, addition, and subtraction are evaluated strictly in standard mathematical order.

What is the maximum number of digits displayed?

The display comfortably shows standard numbers up to 12 digits, automatically switching to scientific E-notation for very large or tiny numbers.

Are my calculations saved or uploaded anywhere?

No. All mathematical expressions are computed strictly in your local browser memory.
