DataType Utility: DataType.Number.format()
The Number module of the DataType Utility allows you to take a number and format it into a string with the following configuration parameters:
decimalPlaces, decimalSeparator, thousandsSeparator, prefix, and suffix.
To output a number as a string, simply call the format() function of the DataType.Number class:
YUI().use("datatype-number", function(Y) { alert(Y.DataType.Number.format(123123123)); // This alerts the string "123123123" });
format() function also takes a variety of configuration parameters that manipulate the value of the string. This is helpful, for instance, when displaying numbers as currency:
YUI().use("datatype-number", function(Y) { alert(Y.DataType.Number.format(123123123.176,{ prefix: "¥", thousandsSeparator: ".", decimalSeparator: ",", decimalPlaces: 2, suffix: " (YEN)" })); // This alerts the string "¥123.123.123,18 (YEN)" });
