How can I make JSON.NET return a decimal instead of a double when parsing floats from JSON? (it's an object with a Dictionary<string,object> that is serialized).
I've tried writing a JsonConverter but the CanConvert method doesn't get called with a Double type in order to try and convert it. There's other code regarding overriding JsonTextReader but this doesn't seem possible in the latest versions of Json.Net.

Numeric types¶. There are two numeric types in JSON Schema: integer and number. They share the same validation keywords. Note. JSON has no standard way to represent complex numbers, so there is no way to test for them in JSON Schema. The integer type is used for integral numbers.
That is, although the spec format name is "double", in JSON or XML this necessarily means "decimal approximation of double", so by converting on the client side back to double you're only approximating an approximation. Having only one level of approximation, taking the decimal conversion, would be better.
In Json.NET, dynamic properties are serialized and deserialized exactly the same as untyped objects: because dynamic isn't an actual type, Json.NET falls back to deserializing the JSON as LINQ to JSON objects. The second usage of dynamic in .NET are by the types that implement IDynamicMetaObjectProvider.
.NET lists (types that inherit from IEnumerable) and .NET arrays are converted to JSON arrays. Because JSON arrays only support a range of values and not properties, any additional properties and fields declared on .NET collections are not serialized.
In Json.NET 5.0, Newtonsoft.Json.JsonSerializerSettings class has the new property FloatParseHandling, you can set this property value Newtonsoft.Json.FloatParseHandling.Decimal
