How to take the length of a string with zero at the end in Javascript?

if the value of the string is as "123.45". The length is coming as 5 which is fine.

But if the value of the string is as "123.40". The length is coming as 4 instead of 5.

Can you post your code of how you are checking the length of your strings please?

String "123.45" has a length of 6. If your code is returning a length of 5 then you must be doing something different to what you say you are doing.

//First Case
var num = 123.40;
str = num.toString();

len = str.length;
alert(len);

//Second Case
var num = 123.45;
str = num.toString();

len = str.length;
alert(len);

1. Reply to comment so that the user is notified.
2. Click improve question and put your code in the actual question instead of in a comment.
3. You can't do it like that because 123.40 is the same exact value as 123.400 and 123.4000 so you'll have to put it into a string or format it with that many places. For example you can do:

JavaScript

var num = 123.40;
num = num.toFixed(2); // this will make sure it always has 2 decimal places so that ending in 0 is accounted for.
