title: how to format the float to 3 decimal in pinescript
body: <p>I m using this <code>alertcondition</code> to ask the value from a plot, but the returned value has more than 3 decimal places. </p>
  
  <p>Can I format it to make the output only display precision until 3 decimals only?</p>
  
  <pre><code>alertcondition(crossover(d2,d3), title="monitor", message='{{ticker}} Monitor If price above Current Price={{close}} PIVOT = {{plot("Pivot")}} SUPPORT = {{plot("S1")}} RESISTANCE = {{plot("R1")}}
  </code></pre>
