# toString abstract method

String toString()
override

Returns a String-representation of this integer.

The returned string is parsable by parse. For any `BigInt` `i`, it is guaranteed that `i == BigInt.parse(i.toString())`.

Example:

    var bigNumber = BigInt.parse('100000000000000000000000');
    print(bigNumber.toString()); // "100000000000000000000000"

## Implementation

    String toString();
