Grouping and decimal separators differ by region, which is why a number can be misread across borders. Indian numbering is the exception that matters most: it groups the last three digits and then pairs, so 12345678 becomes 1,23,45,678 rather than 12,345,678.

What Is Number Formatter?

The Number Formatter formats a number with thousands separators, decimal places, rounding mode, currency, percentage, compact notation, ordinals, Roman numerals, and words. Separator style switches between US, EU, space, and Indian grouping.

Who Uses the Number Formatter?

Developers use it to preview exactly how a number will render for a locale before shipping it, and to sanity check a report or a data feed that mixes separators. Students and writers use the words and Roman numeral output for text that cannot use digits.

How to Use the Number Formatter

  1. Enter a number.
  2. Choose the style, separator, decimal places, and rounding.
  3. Copy the formatted result, or read the words and sign.
