2 ** 256 BigInteger in javascript

问题

Which will normally result in 1.157920892373162e+77 ,but what I want is the accurate number of 2 ** 256 like 1157920892731685487456125.....

I has try big-integer and math.js but both can't show all of the number after calculate.

回答1:

Works fine using big-integer:

const bigInt = require('big-integer');
let value    = bigInt(2).pow(256);

console.log(value.toString());
// 115792089237316195423570985008687907853269984665640564039457584007913129639936
