title: Swiftui specify double format
body: <pre><code>Text("Värde \(Double(calc2, specifier: "%.2f").rounded())") 
  </code></pre>
  
  <p>//ERROR</p>
  
  <p>I am converting a <code>Slider</code> value that uses a double type, but i cant format specify it?
  I get an error and xcode tells me to use signaling(?). I've tried putting it into an <code>Int</code> as well.</p>
  
  <p>whats the right move here?</p>
