Turn numerical string into comma-separated format

Question

Turn numerical string into comma-separated format

In my Angular 2 / Typescript project, I am working with a string that contains numeric values such as the ones listed below:

10000

10000.50

-10000

-10000.50

0

I need to insert commas after every thousand mark in these numbers, like so:

10,000

10,000.50

-10,000

-10,000.50

0

What is the most effective way to achieve this?

I have experimented with different solutions but none of them seem to work perfectly.

For instance, using

this.value.toString().replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,");

and this.value.toLocaleString(); do not handle both the commas and decimal points correctly.

Split the number using "indexOf('.')", then apply a specific method to each part accordingly.

function addCommaToNumber(num){
//perform type checking
var numStr = num.toString();
var intEnd = numStr.indexOf('.');
var onePart =numStr,otherPart ='';
if(intEnd !== -1){
onePart = numStr.slice(0,intEnd); 
otherPart = numStr.slice(intEnd); 
}

return onePart.replace(/(\d)(?=(?:\d{3})+$)/g, '$1,')+otherPart;
}
