64 bit - JavaScript 64 bit numeric precision

Is there a way to represent a number with higher than 53-bit precision in JavaScript? In other words, is there a way to represent 64-bit precision number?

I am trying to implement some logic in which each bit of a 64-bit number represents something. I lose the lower significant bits when I try to set bits higher than 2^53.

Math.pow(2,53) + Math.pow(2,0) == Math.pow(2,53)

Is there a way to implement a custom library or something to achieve this?

Google's Closure library has goog.math.Long for this purpose.
