I was in need to use the number 515236034100068353 but JavaScript transforms it as 515236034100068350
console.log(515236034100068353 === 515236034100068350)
Why does this happens ? How could I fix it ?

I am making a calculator in JavaScript that needs to be able to do precise math on numbers larger than 2^53, which is 9007199254740992. Is there any way to do this?
You can use the "strint" library https://github.com/rauschma/strint.
For example:
> var strint = require("./strint");
> strint.add("9007199254740992", "1")
'9007199254740993'

What is the reasoning? I believe this is the only value not equal to itself in JavaScript.
NaN isn't equal to NaN
Use the IsNaN function to check it
