    Check `console.log( Number.MAX_SAFE_INTEGER )` – hjpotter92 Aug 09 '14 at 04:34
  • Only integers up to 2^53 can be *distinctly* represented - a double is used for all numeric values. This is a duplicate, I am sure. – user2864740 Aug 09 '14 at 04:36

All numbers in JS are 64 bit floating point numbers. the largest integral value is 2 pow 53, or 9007199254740992.
