Large numbers to string in JavaScript

Question

When I do the following:

alert((2053716830872415770228778006271971120334843128349550587141047275840274143041).toString());

I get the "2.053716830872415e+75" exponential notation. I want to alert the number as is. I tried toFixed(), toPrecision() and toLocaleString() and they output the same thing.

How can I accomplish this? Note: the number is a variable, so I cannot alert("208..");

Javascript uses 64-bit floating point numbers.
It is impossible to precisely store your value in a Javascript number.

Instead, you should use a BigInteger library.
