title: Creating autorelease objects in iPhone Development
body: <p>I have a requirement to create some <code>NSDecimalNumber</code> objects objects as part of my application (as I require the precision of calculation they offer) but I note that in calculations they return NSDecimalNumber objects which are, presumably, autoreleased. </p>
  
  <p>My question is really whether this is potentially problematic in an iPhone application where I may carry out lots of calculations.</p>
  
  <p>The question is not just relating to NSDecimalNumber specifically but to the sometimes unavoidable creation of autoreleased objects in the course of developing an iPhone application.</p>
  
  <p>Any detailed answers on this point would be gratefully received. </p>
