title: Converting NSString to a decimal
body: <p>I need to change the code below to make "intAmount" a decimal or an integer (i.e. a person can enter .10 or 1) in my uitextfield. The last line "myProduct" has to be a decimal not an integer and return the product in the format "18.00" for example. Can someone help someone help me alter my code snippit for this?</p>
  
  <pre><code>//amt has to be converted into a decimal value its a NSString now
  NSInteger intAmount = [amt intValue];
  //where total gets updated in the code with some whole (integer) value
  NSInteger total=0;
  //Change myProduct to a decimal with presicion of 2 (i.e. 12.65)
  NSInteger myProduct=total*intAmount;
  </code></pre>
  
  <p>THIS DOESN'T WORK</p>
  
  <pre><code>NSDecimalNumber intAmount = [amt doubleValue];
  //Keep in mind totalCost is an NSInteger
  NSDecimalNumber total=totalCost*intAmount;
  </code></pre>
