How to format a string number with commas?

goldenbear401

I have a string that contains a number, and I want to format it so that it has commas separating the thousands. For example, if my string is "12345", I want it to be formatted as "12,345". How can I do this in JavaScript?

There are a few ways you can format a string number to have commas. One way is to use the built-in function called "format". You can use this function like so:

number = 1234567
print(format(number, ","))

This will print out the number with commas like so: 1,234,567.

Another way to format a string number to have commas is to use the "str.format" method. You can use this method like so:

number = 1234567
print("{:,}".format(number))

This will also print out the number with commas like so: 1,234,567.

The easiest way to do this is to use the "NumberFormat" class:

NumberFormat formatter = NumberFormat.getInstance();
String formattedNumber = formatter.format(1234.56);

This will give you a string with the number formatted with commas, like "1,234.56".
