| * `max_value` Validate that the number provided is no greater than this value. | ||
| * `min_value` Validate that the number provided is no less than this value. | ||
| * `coerce_to_string` Set to `True` if string values should be returned for the representation, or `False` if `BigInteger` objects should be returned. Defaults to the same value as the `COERCE_BIGINT_TO_STRING` settings key, which will be `True` unless overridden. If `BigInterger` objects are returned by the serializer, then the final output format will be determined by the renderer. |

||
| When returning biginteger objects in API representations that do not support numbers up to 2^64, it is best to return the value as a string. This avoids the loss of precision that occurs with biginteger implementations. | ||
|
|
||
| When set to `True`, the serializer `BigIntegerField` class will return strings instead of `BigInteger` objects. When set to `False`, serializers will return `BigInteger` objects, which the default JSON encoder will return as numbers. |

add (by default) after "class", as it can be overridden

Why int('1')?
And why only test the type, not the value itself?
