Overflow error using BigNumber.from

[rahulrumalla]

Hello.

I'm using the Ethplorer API to fetch the balances and when I try to convert these using BigNumber (to display balance in web app), the library throws an error. I'm wondering what the right way to do this is.

Error
Uncaught (in promise) Error: overflow (fault="overflow", operation="BigNumber.from", value=12300000000000000, code=NUMERIC_FAULT, version=bignumber/5.5.0)

API data
https://api.ethplorer.io/getTopTokenHolders/0x2d94aa3e47d9d5024503ca8491fce9a2fb4da198?apiKey=freekey

{
  "address": "0xdc351121342d0d25c80203201386323c1dcc7365",
  "balance": 3.66342855771621e+26,
  "share": 36.63
}

BigNumber.from(1.23e+16) --> works
BigNumber.from(1.23e+17) --> throws an overflow error

For larger integers, consider using BigInt or HexString

Exactly, or use a string.

JavaScript uses IEEE 754 numbers, which are only safe up to 53 bits (2 ** 53), beyond that JavaScript will round, so the values are unsafe. All math operations should be done using BigNumber maths.

The parseUnits("1.0") can also be used to help enter large numbers.

Thanks, both. The suggestions helped. I ended up using BigInt.
