# Put Comma Values in Numbers

This function assumes what is being submitted to it is a string, with a decimal point and two places after the decimal. To get your number into that format first, use this.

Then this function will properly comma separate the number. For example, 2345643.00 will return 2,345,643.00

``````function CommaFormatted(amount) {
var delimiter = ","; // replace comma if desired
var a = amount.split('.',2)
var d = a[1];
var i = parseInt(a[0]);
if(isNaN(i)) { return ''; }
var minus = '';
if(i < 0) { minus = '-'; }
i = Math.abs(i);
var n = new String(i);
var a = [];
while(n.length > 3) {
var nn = n.substr(n.length-3);
a.unshift(nn);
n = n.substr(0,n.length-3);
}
if(n.length > 0) { a.unshift(n); }
n = a.join(delimiter);
if(d.length < 1) { amount = n; }
else { amount = n + '.' + d; }
amount = minus + amount;
return amount;
}``````

is there something like this for PHP?

Ohhh.. Wonderful code snippet. Searching for long time.

this is how I do it:

{
nStr += ”;
var x = nStr.split(‘.’);
var x1 = x[0];
var x2 = x.length > 1 ? ‘.’ + x[1] : ”;
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, ‘\$1′ + ‘,’ + ‘\$2′);
}
return x1 + x2;
}

Jack you function is much better thx. The function from the post is riddled with errors.

Any chance to insert a comma or a space between the numbers in this counter?

kasa=new Date(2008 ,12 ,60 ,30 ,01);
setInterval(function(){
with(Math){
var w=floor(((new Date())-kasa)/1000),lr,dr,mr,
l=floor(w/31536000),d=floor((lr=w%31536000)/86400),
g=floor((dr=lr%86400)/3600),m=floor((mr=dr%3600)/60),
s=floor(mr%60);
document.getElementById(‘money’).innerHTML=
(l?l+’ l., ‘:”)+d+’ dni,’+g+’ godz., ‘
+m+’ min., ‘+s+’ sek.';
}
},1000);
setInterval(function(){
document.getElementById(‘MoneyCounter’).innerHTML=
((new Date())-kasa);
},130);

Here’s the same thing in 1 line. If anybody can do better, do share.

```function commas(str) {
return str.replace(/.(?=(?:.{3})+\$)/g, '\$&,');
}```
6. Can’t do better making it shorter, but I can fix it so it takes numeric arguments!

function commas(str) {
return (str+””).replace(/.(?=(?:.{3})+\$)/g, ‘\$&,’);
}

7. Hmm… and make it handle decimals in a hackish way. ;-)

function commas(str) {return (str+””).replace(/.(?=(?:[0-9]{3})+\b)/g, ‘\$&,’);

function format(input)
{
var num=input.value.replace(/[^\d]/g,”);
if(num.length>3)
num = num.replace(/\B(?=(?:\d{3})+(?!\d))/g, ‘-‘);
input.value=num;
}

9. Hello Chris,

If amount will be 2200 then your var “d” will give an error as undefined variable and script will not execute this script only work when your amount is 2200.00 so I have edited your script and used it in my website ;) below is revised code which might solve this issue.

```function CommaFormatted(amount) { var delimiter = ","; // replace comma if desired var a = amount.split('.',2) var d = a[1]; var i = parseInt(a[0]); if(isNaN(i)) { return ''; } var minus = ''; if(i < 0) { minus = '-'; } i = Math.abs(i); var n = new String(i); var a = []; while(n.length > 3) { var nn = n.substr(n.length-3); a.unshift(nn); n = n.substr(0,n.length-3); } if(n.length > 0) { a.unshift(n); } n = a.join(delimiter); if(d) { if(d.length < 1) { amount = n; } else { amount = n + '.' + d; } } else { amount = n + ".00" } amount = minus + amount; return amount; }```
