-
$_formatters protected static
arrayA 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.
