title: iOS Round Double value to 2 decimal digits and round 3rd decimal digit up
body: <p>I have I double value like this one <code>17.125</code>.
  It should be rounded up to <code>17.13</code></p>
  
  <p>If I use the simple method like <code>%.2f</code> it shows me <code>17.12</code>
  I also followed several methods described in other threads here like using <code>NumberFormatter</code> and so on - but without luck.</p>
  
  <p>Maybe someone has an advice for me to fix this problem? Do I have to round it on my own?</p>
