title: How would you store a number larger than the max 64 bit int in mongoDb?
body: <p>The number is larger than 9223372036854775807 - too big for NumberLong, which is mongo's native 64-bit long type.  What's the best way to do this/the best field type?  </p>
  
  <p>Is it possible to preserve any of the querying functionality of a smaller integer (such as <code>{$lt}</code>)?  </p>
  
  <p>The big numbers are being generated by bignumber.js, and I'm using mongoose to interact with mongoDb. </p>
