A list of number formatters indexed by locale and type

Method Summary

_setAttributes() protected static
Set formatter attributes
config() public static
Configure formatters.
currency() public static
Formats a number into a currency format.
defaultCurrency() public static
Getter/setter for default currency
format() public static
Formats a number into the correct locale format
formatDelta() public static
Formats a number into the correct locale format to show deltas (signed differences in value).
formatter() public static

Returns a formatter object that can be reused for similar formatting task under the same locale and options. This is often a speedier alternative to using other methods in this class as only one formatter object needs to be constructed.
ordinal() public static
Returns a formatted integer as an ordinal number string (e.g. 1st, 2nd, 3rd, 4th, [...])
parseFloat() public static
Parse a localized numeric string and transform it in a float point
precision() public static
Formats a number with a level of precision.
toPercentage() public static
Formats a number into a percentage string.
toReadableSize() public static
Returns a formatted-for-humans file size.

array $options optional []: An array with options.

Returns

NumberFormatter
The configured formatter instance
