Lock up issues and no calculation OR RangeError: Maximum BigInt size exceeded

[ganeshkbhat]

I am trying this var n = bigInt("3").pow("300530164787").minus("3").isDivisibleBy("300530164787"); and var n = bigInt("3").pow("3005301647874556767787878788787").minus("3").isDivisibleBy("3005301647874556767787878788787");and the node console is all locked up.

I am expecting the above to check if isDivisibleBy(value) returns an absolute integer and not a float. 300530164787%1 === 0 and 300530164787.234%1 === 0.234 or value%1 === 0

It also throws an error :

return new NativeBigInt(this.value * parseValue(v).value);
                                           ^

It could ve that the number us too large, try modPow

You probably reached the memory limit. I think the V8 engine will error once you use more than 1 billion bits.

By the way bigInt("3").pow("3005301647874556767787878788787") is a very huge number, I'm not sure that I would expect the calculation to finish within a human lifetime.

As @Yaffle pointed out, if all you want to do is check divisibility, the modPow method should be a lot faster.
