modern browsers, use
Specify a locale tag as first parameter to control the decimal separator. For a dot, use for example English U.S. locale:
which gives:
Most countries in Europe use a comma as decimal separator, so if you for example use Swedish/Sweden locale:
it will give:

4 I would suggest you use
that way you will also have the local format of a country you specify, plus it would garantee to show exact 2 decimals (whether when num is 1 or 1.12345, it will show 1.00 and 1.12 respectively) In this example I used German localization, because I wanted my numbers show with thousands delimiter, so this would be some outputs:

mplungjanmplungjan 159k27 gold badges167 silver badges225 bronze badges 1 If you're already using jQuery, you could look at using the jQuery Number Format plugin. The plugin can return formatted numbers as a string, you can set decimal, and thousands separators, and you can choose the number of decimals to show.
You can also get jQuery Number Format from GitHub. answered Nov 8, 2012 at 23:47

Minas MinaMinas Mina 2,0023 gold badges23 silver badges34 bronze badges Where specific formatting is required, you should write your own routine or use a library function that does what you need. The basic ECMAScript functionality is usually insufficient for displaying formatted numbers. A thorough explanation of rounding and formatting is here: http://www.merlyn.demon.co.uk/js-round.htm#RiJ As a general rule, rounding and formatting should only be peformed as a last step before output. Doing so earlier may introduce unexpectedly large errors and destroy the formatting. answered May 26, 2011 at 5:58

I had to decide between the parseFloat() and Number() conversions before I could make toFixed() call. Here's an example of a number formatting post-capturing user input. HTML:
Event handler:
The above code will result in TypeError exception. Note that although the html input type is "number", the user input is actually a "string" data type. However, toFixed() function may only be invoked on an object that is a Number. My final code would look as follows:
The reason I favor to cast with Number() vs. parseFloat() is because I don't have to perform an extra validation neither for an empty input string, nor NaN value. The Number() function would automatically handle an empty string and covert it to zero. answered Oct 12, 2018 at 19:18

1 RegExp - alternative approachOn input you have string (because you use parse) so we can get result by using only string manipulations and integer number calculations
