How to avoid scientific notation for large numbers in JavaScript?

Question

JavaScript converts a large INT to scientific notation when the number becomes large. How can I prevent this from happening?

Answer 1

If you are just doing it for display, you can build an array from the digits before they're rounded.

var num = Math.pow(2, 100);
var reconstruct = [];
while(num > 0) {
    reconstruct.unshift(num % 10);
    num = Math.floor(num / 10);
}
console.log(reconstruct.join(''));
