  }
  catch (NumberFormatException e) {
    throw new PrestoException(INVALID_CAST_ARGUMENT, format("Cannot cast VARCHAR '%s' to DECIMAL(%s, %s). Value is not a number.", stringValue, precision, scale));
  }
  if (overflows(result, precision)) {
    throw new PrestoException(INVALID_CAST_ARGUMENT, format("Cannot cast VARCHAR '%s' to DECIMAL(%s, %s). Value too large.", stringValue, precision, scale));
  }
  return result.unscaledValue().longValue();

protected Node visitBinaryLiteral(final BinaryLiteral node, final Object context) {
 // May need some changes.
 // use an if/else block here (instead of isPresent.map(...).orElse(...)) so only one object
 // gets instantiated (issue #1784)
