Json.NET decimal serialisation issue

If I have a decimal that represents some Japanese Yen (i.e. exponent zero currency) amount e.g. 3131313, I see Json.NET serialising the value to 3131313.0 by default.

Is there any way to get it to serialise the literal value 3131313 instead?

By implementing your own converter you can serialize as

var str= JsonConvert.SerializeObject(
     new {s="aaa",d=(decimal)3131313},
     new MyConverter());

-

public class MyConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        if (objectType == typeof(decimal)) return true;
        return false;
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        writer.WriteValue(Convert.ToInt64(value));
    }
}
