Since you are just displaying it, why not convert it to a string? That is what I'd do. Seems like JavaScript numbers are floating point to 15 digits; so I believe that is all you can do.

Not clear. How it should be displayed and how it is actually displayed? What's the problem? What are the mantissa and order limits you want to have?

JavaScript does not support so big integers. If you enter the assignment to such literal in JavaScript, it will be parsed to Infinity.

One of the possible work-around solution would be using a BigInteger library for JavaScript. Consider, for example, this: http://silentmatt.com/biginteger[^].
