View Full Version : Splitting a Number

Howdy, it's my inquisitive self again.

I am curious as to if JavaScript has a specific command to split a number like 1267618, and add commas where needed, so it would make 1,267,618?

If there ISN'T, then do you have a script that could do it? I don't think my way is that effective, since it's so bulky...


var random = 66298762343;
var random2 = "";
var random3 = String(random);
var temp = 0;
for (b=random3.length;b>=0;b--) {
if (temp >= 3) {
temp=0;
random2 = ","+random3.charAt(b)+random2;
} else {
random2 = random3.charAt(b)+random2;
}
temp++;
}
if (random2.charAt(0) == ",") {
random3 = "";
for (a=1;a<random2.length;a++) {
random3 = random3+random2.charAt(a);
}
random2 = random3;
}
alert(random2);


See? It doesn't look too good for just adding it to ONE number. Any help is greatly appreciated, since this has been annoying me for awhile (just the bulkiness of it).
adios

Here's another solution. Of course not as elegant as the regular expression solution from the above link but was a fun exercise in recursion.:cool:


<html>
<title>Inserting commas into a number</title>

<head>
<script type="text/javascript">

function commaTize (theNumber) {
var thisPiece = new String();
var NewNbr = new String ();

if (theNumber.length >= 4) {
thisPiece = "," + theNumber.slice (theNumber.length-3, theNumber.length);
theNumber = theNumber.slice (0, theNumber.length-3);
NewNbr = commaTize (theNumber);
}else{
thisPiece = theNumber;
theNumber = "";
}

NewNbr = NewNbr + thisPiece;
return NewNbr;
} // commaTize ()

</script>
</head>

<body>
<script type="text/javascript">
var original = new String ("123456789");
var commaNbr = new String ();

document.write ("Here is the original number: " + original + "<BR>" );
commaNbr = commaTize(original);
document.write ("Here is the number w/ commas: " + commaNbr + "<BR>");
</script>
</body>
</html>


Man, I gotta learn RegExp's !!!:eek:
