Most people who read this are not Flash developers, but I know some of you are, so I thought I’d post this little script I made.
I searched all over the web for a simple function that would format numbers nicely in Flash. I couldn’t find one I liked, so I put this one together. Feel free to copy and paste it as you will, if you think you might find it useful.
It takes 4 parameters – the number you’d like to format, the number of digits you’d like for the decimal, the strign you’d like to use as a seperator for thousands, and the string to use for the decimal character.
function numberFormat(myNum:Number, precision:Number, seperator:String, decimal:String) {
// get a string
myString = String(myNum);
// if there is a decimal…
if (myString.indexOf(".", 0) != -1) {
decimalIndex = myString.indexOf(".", 0);
decimalNum = myString.substring(decimalIndex, myString.length);
// otherwise
} else {
decimalIndex = myString.length;
decimalNum = ".";
}
// split the number at the decimal
number = myString.substring(0, decimalIndex);
// make a new var that we will create with the commas
newNumber = "";
// add the commas…
for (i=number.length-1; i>=0; i--) {
newNumber = newNumber+number.charAt(number.length-1-i);
if ((i%3 == 0) and (i != 0)) {
newNumber = newNumber+seperator;
}
}
// now make the decimal side - first, trim off the "."
decimalNum = decimalNum.substring(1, decimalNum.length);
// if it's the appropriate number of digits already, we are done!
// otherwise…
if (!(decimalNum.length == precision)) {
// if we just need to add zeros,
if ((decimalNum == 0) or (decimalNum.length0) {
return newNumber+decimal+decimalNum;
} else {
return newNumber;
}
}
trace(numberFormat(123456789, 0, ",", "."));
// returns "123,456,789"
trace(numberFormat(12345.6789, 1, " ", ","));
// returns "12 345,7"
trace(numberFormat(12345678.9, 2, ",", "."));
// returns "12,345,678.90"
