title: PayPal Rest API error that sum does not add up but it does
body: <p>I am using PayPal Rest API (SDK for Java) and when I submit a payment for excution (i.e. before the redirect) I get the error: </p>
  
  <pre><code>  Excetpion e [{
    "field": "transactions[0]",
    "issue": "Item amount must add up to specified amount subtotal (or total if amount details not specified)"
  }]]]
  </code></pre>
  
  <p>However the numbers are as follows (copy from my debug log) and add up and particularly the price of all items (there is only one) is exactly the subtotal</p>
  
  <pre><code>[[ tranaction t total 24.57]]
  [[ tranaction t subtotal 19.8]]
  [[ tranaction t tax 3.92]]
  [[tranaction t shipping 0.85]]
  [[tranaction t item[0] price 19.8]]
  </code></pre>
  
  <p>Anybody an idea whats up there?
  Cheers
  Tom</p>
