How to display the exchange rate in this ajax?

Question

JavaScript

Good time of the day.
Tell me how to display the exchange rate in this ajax
Here is the ajax code

$.ajax({
  method: 'GET',
  url: 'js/currency.php',
  success: function(response){
    var json = JSON.parse(response);
    json.Valute.forEach(function(e){
      if (e['@attributes'].ID == 'R01235') console.log(e.Value);
    });
  }
});

Now prints the value to the console.
How to change the value, that is, now the value is 56.9359 , cut off the back digits in this case 59 and assign the value to a variable with output on the page?
Help with a solution.

Answer 1

Here you can read how to round a number or bring it to the form you need.
To assign a number to a variable:
if (e['@attributes'].ID == 'R01235') var cur = e.Value;
And output this number to some input:
use jQuery
$('#id_iput').val(cur);

Answer 2

jquery append would be the simplest solution.
As for string truncation, there are many solutions, but I would advise you to master regular expressions. A very powerful tool that is always needed.
