title: golang how to remove %!d(string= in string
body: <p>I have this:</p>
  <pre class="lang-golang prettyprint-override"><code>newStr := fmt.Sprintf(&quot;new price: %d€&quot;, newPrice)
  fmt.Println(newStr) // new price:  %!d(string=500.00)€
  // except I want: new price: 500,00€
  </code></pre>
  <p>How to remove the <code>%!d(</code> and the <code>)</code> at the end of the string so it can be like this <code>new price: 500,00€</code></p>
  <p>I could use a format the <code>strings.Replace</code> but I don't think it's the good answer.</p>
  <p>My <code>newPrice</code> is a float.</p>
  <p>I'm pretty sure it as already been ask but it's hard to google those kind of things.</p>
