How to use 64-bit Integer in Javascript to avoid the overflow?

Answer 1

XXX js has types, even if js variables are not typed ^^

anyway, js has no 'long' type... only float numbers (and internally 32 bits signed integer) wich impose integer upper limit at 2^53.

however, modern js have BigInt object, wich could handle arbitrarily large integers:

... or you could use TypedArray wich provide 64 bits models (float, int, uint) since your browser do support BigInt:

Answer 2

visph yeah I meant to say that you can't 'specify' types for variables in JavaScript.

And thanks for the additional info though. I didn't know JavaScript has BigInt too. I'll delete my answer because it's wrong👍

Answer 3

Use "long" datatype for it
