Serializing double.MaxValue is incorrect

[vwxyzh]

double.MaxValue will be serialized as 1.79769313486232E+308
but the real value should be 1.7976931348623157E+308, when deserializing, it will throw OverflowException.

repro:

var s = new Serializer();
var sw = new StringWriter();
s.Serialize(sw, new Dictionary<string, double> { ["a"] = double.MaxValue });
Console.WriteLine(sw.ToString());
var d = new Deserializer();
d.Deserialize<Dictionary<string, double>>(new StringReader(sw.ToString()));
