title: How to format float to 2 decimals in objective C
body: <p>I have a string that I'm converting to a float that I want to check for values in an if statement.</p>
  
  <p>The original float value is the iPhone's trueHeading that is returned from the didUpdateHeading method. When I convert the original float to a string using @"%.2f" it works perfectly, but what I'm trying to do is convert the original float number to the same value. IF I just convert the string to [string floatValue] I get the same original float number, and I don't want that.</p>
  
  <p>To make it short and simple, how do I take an existing float value and just get the first 2 decimals?</p>
