FAQ & notes
Can I divide by zero?
No. When the second value is zero and divide is selected the calculator returns “undefined” to highlight the invalid operation.
Does the calculator handle very large numbers?
Yes. Outputs greater than one million automatically switch to scientific notation while preserving the computed precision.
