title: Angular HttpParams Set Number Value Error
body: <p>I want to send the data I getfrom the form with angular to the backend. But I get an error when I add number value tı (params.set) part.</p>
  <p>Error:Argument of type 'number' is not assignable to parameter of type 'string'.</p>
  <pre><code>Name=ALex (string)
  No:323678(number)
  
  this.personel.name = this.form.get(&quot;name&quot;).value;
  this.personel.no = this.form.get(&quot;no&quot;).value;
  
  
  let params = new HttpParams();
  
  if (personel.name != '')
    params = params.set('name', personel.name);
    
  if (personel.no != '')
    params = params.set('no', personel.no);
  </code></pre>
  <hr />
  <pre><code>export class Personel {
  
        personelId:number;
        name:string;
        surname:string;
        no:number;
