We usually assign the received user input (=POST variables) to the model before performing other operations (calculations, validaton, saving, etc.).<br>
Therefore we sugges to do the 'unformatting' during the assignment process. This way, after one of the following lines is executed:

```php
$product->attributes = $_POST['Product']; // or ...
$product->setAttribute('price', $_POST['Product']['price']); // or ...

    if (stripos($column->dbType, 'decimal') !== false) // new
 
      $value = Yii::app()->format->unformatNumber($value); // new
 
    if(property_exists($this,$name))
 
      $this->$name=$value;
 
    else if(isset($this->getMetaData()->columns[$name]))
 
      $this->_attributes[$name]=$value;
 
    else
 
      return false;
 
    return true;
 
  }
 
}
```

Derive all models from this new ActiveRecord class. For example in the Product model `models/Product.php` edit the following line:

```php
