Frequently Asked Questions

How do I use the online calculator?

Simply click the number and operation buttons to perform calculations. You can also use your keyboard for faster input. The display shows your current input and the history area shows recent calculations.

Does the calculator support scientific functions?

Yes, our calculator includes scientific functions like square root (√), percentage (%), reciprocal (1/x), and sign change (+/-). More advanced scientific functions may be added in future updates.

Can I use keyboard input with the calculator?

Absolutely! You can use numbers (0-9), operators (+, -, *, /), decimal point (.), Enter for equals, Escape to clear all, and Backspace to clear the current entry.

How do the memory functions work?

MC clears memory, MR recalls the stored value, M+ adds the current display to memory, and M- subtracts the current display from memory. The memory indicator shows when a value is stored.

What's the difference between C and CE?

C (Clear) resets the entire calculator including memory and history, while CE (Clear Entry) only clears the current input, allowing you to continue with your calculation.

How accurate are the calculations?

The calculator uses JavaScript's built-in math functions and provides standard floating-point precision. Results are formatted to avoid excessive decimal places while maintaining accuracy.
