title: Compare very large numbers stored in string
body: <p>What is the best way to compare two very large numbers contained in string literals?</p>
  
  <p>For example I want to compare the followings:
  "90000000000000000000000000000000000000000000000000000000000000000000000000001"
  "100000000000000000000000000000000000000000000000000000000000000000000000000009"</p>
  
  <p>or</p>
  
  <p>"0000000000111111111111111111111111111111111111111111111111111111111111111111"
  "0000001111111111111111111111111111111111111111111111111111111111111111111111"</p>
  
  <p>In both cases obviously the second one is greater, but how could I find it out efficiently without iterating on elements?</p>
