CLDR identifies locales and currency decimal precision. ECMAScript Intl formats a valid decimal and Gregorian date in UTC, avoiding a date shift from the viewer’s time zone. Search results include only locales this browser supports.

Worked example: 12345.67 in en-US displays as 12,345.67; USD uses two decimals. In de-DE the grouping and decimal separators reverse. KWD uses three decimals; JPY uses zero. A blank or invalid input displays an error, never a fabricated zero.

Only 15 significant input digits are accepted. Currency rounding is display rounding, not exchange-rate conversion. Cash rounding increments and non-Gregorian calendar conversion are not implemented. This formatter is not a tax calculator.
