Frequently asked questions
How is the thousands grouping applied?
The integer part is split into groups of three digits from the right, then joined with your chosen separator. The sign stays in front.
Can I use European formatting?
Yes. Set the thousands separator to a dot and the decimal separator to a comma to get values like 1.234.567,89.
What if I do not set decimal places?
The number keeps its own decimals. Set a decimal count to round to a fixed number of places, for example two for currency.
Are negative numbers handled?
Yes. Negatives keep a single leading minus sign, and grouping is applied only to the digits, so you get values like -1,234.50.
Is anything sent to a server?
No. Formatting happens entirely in your browser, so your numbers never leave your device.
