Frequently Asked Questions

How accurate is this calculator?
This calculator provides accurate results for basic arithmetic operations. However, due to the way computers handle floating-point numbers, there might be small rounding errors in some decimal calculations, which is normal for all digital calculators.
Can I use keyboard shortcuts?
Yes! You can use your keyboard for faster calculations. Use number keys for digits, +, -, *, / for operations, Enter for equals, and Escape for clear. The backspace key also works to delete the last digit.
What happens if I divide by zero?
If you attempt to divide by zero, the calculator will display "Error" as division by zero is mathematically undefined. You'll need to clear the calculator to continue with new calculations.
Is there a limit to the number size?
Yes, this calculator can handle numbers within JavaScript's numerical limits. For extremely large or small numbers, scientific notation may be used. If a number exceeds these limits, "Overflow" will be displayed.
