Returns a pattern string to format and parse numbers according to the client's user preferences.
navigator.globalization.getNumberPattern(successCallback, errorCallback, options);
Returns the pattern to the successCallback with a properties object as a parameter. That object contains the following properties:
pattern: The number pattern to format and parse numbers. The patterns follow Unicode Technical Standard #35. (String)
symbol: The symbol to use when formatting and parsing, such as a percent or currency symbol. (String)
fraction: The number of fractional digits to use when parsing and formatting numbers. (Number)
rounding: The rounding increment to use when parsing and formatting. (Number)
positive: The symbol to use for positive numbers when parsing and formatting. (String)
negative: The symbol to use for negative numbers when parsing and formatting. (String)
decimal: The decimal symbol to use for parsing and formatting. (String)
grouping: The grouping symbol to use for parsing and formatting. (String)
If there is an error obtaining the pattern, then the errorCallback executes with a GlobalizationError object as a parameter. The error's expected code is GlobalizationError.PATTERN\_ERROR.
The options parameter is optional, and default values are:
{type:'decimal'}
The options.type can be decimal, percent, or currency.
When the browser is set to the en\_US locale, this should display a popup dialog with text similar to the results that follow:
navigator.globalization.getNumberPattern(
function (pattern) {alert('pattern: ' + pattern.pattern + '\n' +
'symbol: ' + pattern.symbol + '\n' +
'fraction: ' + pattern.fraction + '\n' +
'rounding: ' + pattern.rounding + '\n' +
'positive: ' + pattern.positive + '\n' +
'negative: ' + pattern.negative + '\n' +
'decimal: ' + pattern.decimal + '\n' +
'grouping: ' + pattern.grouping);},
function () {alert('Error getting pattern\n');},
{type:'decimal'}
);
Results:
pattern: #,##0.### symbol: . fraction: 0 rounding: 0 positive: negative: - decimal: . grouping: ,

The pattern property is not supported, and retuens an empty string.
The fraction property is not supported, and returns zero.
