In addition to ordinary numeric values, the numeric type has several special values: Infinity -Infinity NaN WebSerialization format: - Each field is serialized in order, by calling from_bytes/__bytes__. - For Lists, there is a 4 byte prefix for the list length. - For Optionals, there is a one byte prefix, 1 iff object is present, 0 iff not. All of the constituents must have parse/from_bytes, and stream/__bytes__ and therefore be of fixed size. how to set up duplicate screens
