Here is how to use actionscript to format a number in Flash with commas per thousands.
my_number = “12587654325″;
// array in sections of 3 to separate with commas
trace(my_number);
var dollar_array:Array = new Array();
var start:Number;
var end:Number = my_number.length;
trace(my_number.length);
while (end > 0) {
trace(end);
start = Math.max(end – 3, 0);
dollar_array.unshift(my_number.slice(start, end));
end = start;
}
// assign a comma delimited value from dollar_array
my_number = dollar_array.join(“,”);
trace(my_number);

Thanks. With a little conversion of extended characters to regular ones (like the fancy “” to regular quotes), this works nicely. Providing this form allows all the characters, here’s this code converted into a function:
private function commify(my_number:Number):String {
// array in sections of 3 to separate with commas
var strNumber:String = my_number.toString();
var dollar_array:Array = new Array();
var start:Number;
var end:Number = strNumber.length;
while (end > 0) {
start = Math.max(end – 3, 0);
dollar_array.unshift(strNumber.slice(start, end));
end = start;
}
// assign a comma delimited value from dollar_array
return dollar_array.join(“,”);
}
