text: ### Problem
  
  You're displaying formatted values in user inputs as currency with
  [Accounting.js][accounting] and need to remove the decoration to set the
  attributes upstream.
  
  ### Solution
  
  Make use of the [computed property's setter][setters] to remove the
  display formatting and set the property to the proper value.
  
  ```javascript
  formattedAmount: function(key, value) {
    if (arguments.length > 1) {
      // setter
      var cleanAmount = accounting.unformat(value);
      this.set('amount', cleanAmount);
    }
    
    return accounting.formatMoney(this.get('amount'));
  }.property('amount')
  ```
