How to get rid off extra decimals

Question

I have a response which is sending me a value of 0.0554

And the following is my code to convert it into a percentage and display it.

  var m_e = JSON.parse(JSON.stringify(data)).moe;
  console.log(m_e); //here I am getting 0.0554
  var e = m_e*100;
  console.log(e); //here I am getting 5.539999999999999
  $('#element').html('&plusmn;' + e + '%');

And as a result I am getting this enormous value. But I want to print 5.54 only.

Where am I going wrong?

Any kind of help will be greatly appreciated. Thanks.

@AnkitAgarwal It takes time to find duplicates - which you could also have done yourself!! — gurvinder372, Mar 30 '18 at 10:43

You can use toFixed(2) to get two digits after the decimal point:

var data = {
  "moe" : 0.0554
}

var m_e = JSON.parse(JSON.stringify(data)).moe;
  console.log(m_e); 
  var e = m_e*100;
  console.log(e); 
  $('#element').html('&plusmn;' + e.toFixed(2) + '%');
