You can use the toFixed() method to do this. The code below will log the result you want in the console of your browser.

var num = "123456789012.00";
console.log(parseFloat(num).toFixed(2));

A float uses the precision it needs (that's why it's called a "float" -- as in "floating point", the point has no fixed position).

If you want to display a float with the 2 significant digits (i.e. 2 digits after the point), you can use toFixed(2). That will not change the number, but will store it in a string with the number of digits you want to show.
