title: implementing cantor pairing function in iOS
body: <p>I have a implementation of the <strong>Cantor Pairing Function</strong> in Java which I wrote 
  2 years ago. Now then I'm moving more to iOS I need the same thing in Objective-C.</p>
  
  <p>The problem is, at least from my point of view, in Java I had to implement a <strong>BigSqrt</strong> Class 
  which I did by my self. Because theoreticaly I can now Pair any size of number. </p>
  
  <p>Because I am new to iOS I really do not know if I have to implement all the things again for objective-C or is there something already implemented. If so, could someone give me a hint where to start implementing the <strong>Cantor Pairing function</strong> for any size of "Integer" in <strong>Objective-C</strong> ? </p>
  
  <p>thanks </p>
