title: how to format number in wanted format- angular js
body: <p>I have number in this format 7873 and I need to convert it in this format 7'873.</p>
  
  <p>The second format I have is 3564.55443 and I need to format it to 3564.5. For the second format I used number:1 filter, but it formatted it like 3,564.5, but I don't need the comma in the front.</p>
