title: What is the convenience method to compare two NSNumbers with float values using limited precision?
body: <p>What is the Objective-C convenience method for comparing a couple of NSNumbers with float values to see if they are roughly equivalent (two decimal places of precision is fine)? </p>
  
  <p>I would use something other than floats if there was an option that did not change the number around randomly. But anyway I'm already using floats so... .</p>
  
  <p>I imagine there must be something like:</p>
  
  <p>[myNumber isEqualTo:myOtherNumber withPrecision:2];</p>
  
  <p>But actually, amazingly I can't find such a convenience method. What am I missing here? </p>
  
  <p>Would it help to cast the two numbers to NSDecimal or something?</p>
