Inconsistency in PointField

For gis PointField, we are accepting lat and long as numbers/floats but converting them from model field to json as strings. Here https://github.com/Hipo/drf-extra-fields/blob/master/drf_extra_fields/geo_fields.py#L64-L67

Input:

{
        "latitude": 49.8782482189424,
         "longitude": 24.452545489
}

Output:

{
        "latitude": "49.8782482189424",
         "longitude": "24.452545489"
}

Do we have any reasoning for this? I think we should output lat and long as floats.
