You want to format a number with a custom decimal delimiter, thousands delimiters, and/or leading spaces.
Create a
custom Math.formatNumber(
)
method.
ActionScript does not include a built-in way to format numbers as strings, so you need to create a custom method to handle this for you. Furthermore, the delimiter used to indicate decimals and thousands varies by country. For example, the number represented as 1,234.56 in the United States is written as 1.234,56 in many countries. Using some basic string, array, and mathematical methods, we can create a custom method to format numbers with a configurable decimal delimiter (i.e., 123.4 or 123,4), configurable thousands delimiters (i.e., 1,234 or 1.234), and optional leading spaces (to align values when using a monospace font).
Our custom Math.formatNumber( )
method accepts
four parameters:
num
The number you want to format
thousandsDelim
The value to use for delimiting the thousands, millions, billions, etc. places
decimalDelim
The value to use for delimiting the decimal places
spaceFill
Specifies the number of total spaces the formatted string should occupy (optional)
Here is our method definition, which can be added to
Math.as
for easy inclusion in your projects:
Math.numberFormat = function (num, thousandsDelim, decimalDelim, spaceFill) { // Default to a comma for thousands and a period for decimals. if (thousandsDelim == undefined) {thousandsDelim = ",";} if (decimalDelim ...
