I need to convert a string to BigInt like BigInteger
in Javascript
Example
var reqId = "78099864177253771992779766288266836166272662";
var result = parseInt(reqId);
document.write(result);
Resultant value not matching since JavaScript only allows integers up to (2^53)-1.
Is there any way to overcome this?
BigInt
is now a native JavaScript language feature. It's at Stage 3 in the TC39 process and it's shipping in V8 v6.7 and Chrome 67.
To turn a string containing a valid numeric literal into a BigInt
, use the global BigInt
function:
const string = '78099864177253771992779766288266836166272662';
BigInt(string);
// 78099864177253771992779766288266836166272662n
If you just want to hardcode the numeric value into your code, there is no need to convert from a string; use a BigInt
literal instead:
const value = 78099864177253771992779766288266836166272662n;
