Frequently Asked Questions
Can I choose the decimal separator?
Yes. The selected locale determines the standard decimal and grouping separators.
Can the formatter round numbers?
Yes. You can define the minimum and maximum number of decimal places, which may round the displayed value.
Does formatting change the underlying value?
The displayed representation may be rounded, but the original input value should remain available unless you explicitly replace it with the formatted result.
Are my numbers uploaded?
No. Number formatting runs locally in your browser.
