let a = new BigNumber(273862376557801659) console.log(a.toNumber()) // 273862376557801660

You need to pass strings to BigNumber:

BigNumber('273862376557801659')

Libraries like this exist to get around problems with the native number-type, which is the cause of your problem, so try to avoid using it and work with strings as much as possible.
